CydandClaude Fable 5 db7745fcd0 sda4: commit the Glaze developer hard-drive dump 
Un-ignored: the dev drive is the ground truth the restoration and
emulator work constantly reference (DPL3/LIBDPL + VRENDER i860 renderer
source, BT/RP live+dev game trees, VGL_LABS pod boot, scene/audio
content). Kept in-repo for the pod-owner community.

Raw Blame History

PC Telnet is compiled with Microsoft C/C++ 7.0 and MASM 5.1
BUGS FIXED FOR NCSA Telnet 2.3.08 RMG 941114
1) Help screen keys limited to avoid paramater menu.
2) Fixed redraw for console when no open connections.
3) Command line usage display added newlines.
4) BOOTP repaired to not crash packet drivers.
5) GIN repair patch added.
6) Improper fragmentation identification fixed (Solaris users will notice).
7) Net14 uses port=xx option in config.tel
8) Ftpbin cursor repositions after shell out.
9) More GIN tuning
10) Ftpbin control messages all shown.
11) ^Zs removed from ASCII transfers
12) Ftpbin internal more fixed.
13) UDP portlist structure minimized.
14) FTP mget response fixed.
15) Alt-T reloads keymap.
BUGS FIXED FOR NCSA Telnet 2.3.07
1) Alt-E shells no longer crash. The /Gs compiler option had to be added.
2) 0 Byte transfers fixed. For the most part. Blank files are still created
in some circumstances, but it no longer crashes.
3) Hierarchical FTP permissions implemented. See ftpnew.txt
(**Password file format changed**)
4) Setclock revised for MSC 7.0
5) Local printing control amended. ^[[4i? and ^[[5i parsed.
6) Config.tel seconds/ticks resolved. Everything is in seconds now.
(**Config.tel file format changed**)
7) Outgoing CR mapping changed. Options for CR, or LF or CRNUL.
8) Net14.not (note) corrected. And example Net14 session added.
9) Net14 repaired.
10) UDP support enhanced. A small change that won't affect anything.
11) Window resize response makes sense. Resize will now work.
12) Colors fixed. Colors are stable. This means FTP will be visable, and
color info will return when switching among sessions.
13) FTP mget * will not try to get parent dir. Removed . and .. from NLST.
14) TCP reset port code corrected. Code donation by Hsiao-yang Cheng.
15) IP fragments now supported. Code donation by Matthew Kaufman.
16) Ftpbin output redirection improved. Ftpbin now uses ncsaio.asm routines.
17) Keyboard file read from specified location. Keyboard file was read in
from the directory Telnet was started from regardless of config.tel
settings.
18) Scrollback past first screen fixed. Cut n Paste now work from any point
in scrollback.
19) Scrollback text copied after second spacebar. It is no longer necessary
to hit Alt-C, although this still works.
20) Help & DOS-shell work from status screen. You no longer need to have a
connection open to get help or shell out to DOS.
21) Couple other small things, somewhere, probably.
BUGS FIXED FOR NCSA Telnet 2.3.06
1) When FTP'ing to a PC running this Telnet, directories now show up in the
'ls' (NLST) command.
2) Alt-I no longer gives you the time of day.
3) Fixed retransmission bug which caused flooding of network with duplicate
packets. There's another similar bug still reported out there.
4) Vsinterf.c changed to facilitate some ASCII graphics.
BUGS FIXED FOR NCSA Telnet 2.3.05
1) The Telnet Linemode option support has been fixed and enhanced, and
should not cause further problems. (This should fix the IAC SUSP
problems that various people have reported)
2) RARP bugs tracked down and fixed.
3) Telnet is much more consistant about restoring the video modes when
entering, exiting and shelling out to a DOS shell. It will always
try to restore the previous video mode it had been in.
4) Several hidden bugs were fixed in the TCP/IP kernel, which caused
a variety of mysterious crashes and error conditions (including the
'TCP in unknown state' error while FTP'ing files).
5) NET14 program had a timing bug fixed so that it shouldn't corrupt the
TCP/IP stack and crash.
6) When output mapping is engaged, Telnet attempts to negotiate binary
mode for that connection. (This may still cause some problems with
the implementations of binary mode on various hosts...). Also,
corrected screen updating when switching between sessions with
output mapping enabled.
7) Fixed a bug in the rexec/rsh utilities which weren't shutting down the
network correctly and causing further accesses with packet drivers
to fail.
8) Stopped TCP/IP messages from being displayed in printouts using the
VT100 local printer escapes.
9) Plugged more memory leaks.
10) Fixed several obscure Kermit key mapping problems (mostly with \d
mapping).
11) Stopped flushing the ARP cache in certain situations which were
flooding the network with packets.
12) Corrected several vt100/vt220 keyboard mappings in the telnet.key
file.
13) Fixed problem with Telnet refusing to connect to hosts on a Class A
network with host ID of zero. (If you don't know what I'm talking
about, it wasn't affecting you :-)
14) Stopped the vt100 terminal emulation from "eating" ESC chars when they
didn't begin a vt100 command, they are now printed.
15) Added a new machine specific option to the config.tel, called
consoledebug=[0|1|2]. This option controls how much debugging
information about a connection is displayed in the telnet console
window. If consoledebug=0 for a machine, no connection information
is displayed about connections to that machine (this has the least
impact on the speed of Telnet). If consoledebug=1 for a machine,
Telnet Option Negotiation for that machine is displayed on the
console screen (this has only a very mild impact on the speed of
Telnet). If consoledebug=2, the Telnet Option Negotiation and
all data received on a connection is displayed on the console
screen in Telnet (this level of debugging has a significant impact
on the performance of Telnet and should be avoided unless actually
tracking down a problem).
16) Added a new machine specific option to the config.tel file called
outputmap=[yes|no]. This option determines whether Telnet tries
to initially use binary mode in connections to a machine and also
enables output mappping for displaying text from that machine.
Known Bugs: (If these are affecting you, please respond to me personally,
I would like to have some people who can give me some hard data. I
will not (repeat _not_) reply to other bug reports, they should go
to pctelbug@ncsa.uiuc.edu)
1) For some particular cases the Tektronix emulation is not clearing the
screen. (I especially would like somebody to give me a tektronix
file which could reproduce this reliably)
2) LPR/LPQ/LPRM may not work reliably with a packet driver. (which
packet driver(s) would help me a lot)
3) Telnet does not connect to a SCO UNIX system, it drops the connection
somehow. (Need people with Sniffers for the network to let me
know where the problem is)
BUGS FIXED FOR NCSA Telnet 2.3.03
1) Screen modes should be restores more reliably
2) Dos shells now use the telnet screen mode
3) -n command line option disables screen restore
*** NOTE - there is a problem with some video modes on some systems. Telnet
will crash before actually entering the program in this case - I don't
know what is causing it, but if this happens, use an older version.
BUGS FIXED FOR NCSA Telnet 2.3.02:
1) The problem with screen dumps and the problem with ALT-F with VAXs has
been fixed - Telnet was using <LF><CR> instead of <CR><LF>
2) Bootp problems have been fixed
3) AppleTalk should work again
4) Telnet should pay attention to Source Quench messages
5) Shelling to dos from ftp (or from ftp'ing back to your machine
withing telnet) should not cause problems any more
6) FTP messages have been made more informative - both to the user and
on the console screen (internal ftp server)
7) environment variables NCSA01 - NCSA99 now override options in the config.tel
file - user ~ instead of = (set NCSA01="video~vga50;ftp~no")
8) -e option has been added to telbin.exe to override both config.tel and
environment variables (-e "option=something")
BUGS FIXED FOR NCSA Telnet 2.3.01:
1) The problem with packet drivers not working at all is gone. The problem
was with MSC 6.00 and optimizations. MSC was "optimizing" packet driver
support out of telnet
2) A minor bug with linemode was fixed. The case of an option that NCSA
telnet supported and the remote host did not was not handled correctly.
BUGS FIXED FOR NCSA Telnet 2.3-final:
1) Linemode works correctly (for the most part). Some strangeness occurs
with recurring subnegotiation with NeXTs, but this appears to be the
NeXTs doing.
2) Telnet now uses a UNIX style services file (services= in config.tel)
to determine the destination of a packet received on an invalid port.
It will always tell the port number and source ip address, and if an
entry for the tcp port exists in the services file - the destination
application according to services, otherwise unknown.
3) A new beep=(yes/no) entry in config.tel has been added. This is useful
when multiple sessions are open and one of them beeps. The beeping
session gets a pair of musical notes (ASCII 14) in its status
indicator on the status bar.
4) Telnet now attempts to restore the screen on exit.
BUGS FIXES FOR NCSA Telnet 2.3b15:
1) The mouse driver for cut & paste and scrollback operations is now
functional- The left and right mouse buttons are mapped as below (in
the b14 fixes), but when in scrollback mode, pressing and holding the left
mouse button, then pressing the right button will do an "Alt-C" to capture
a highlighted area of text, and then in non-scrollback mode, pressing and
holding the right button and then pressing the left will do the equivalent
of an "Alt-V" paste operation- This allows you to do cut&paste operations
without touching the keyboard. Nifty, huh! :^)
2) Turbo C make has been improved (NOTE: I did _NOT_ say it has been fixed-
I don't have Turbo C on my machine, so I haven't tested it. However, I
have fixed a lot of bugs/discrepancies that impeded TC compiling.)
3) Background FTP tasks in Telnet no longer change your current directory.
4) FTP help has been re-alphabetized.
5) DEC VT100 Local Printer Escape sequences are now supported- ESC [5i now
sends output to the screen AND the local printer (LPT1:) if attached, and
ESC [4i switches the output back to screen only.
6) A "TELNET.PIF" file is now included for using NCSA Telnet within Microsoft
Windows (tm) ver 3.0. This is not guaranteed to work, but it works for me.
BUGS FIXES FOR NCSA Telnet 2.3b14:
1) Configurable ftp-back-to-PC string. This should normally be set to "-n"
to avoid the "Username:" prompt.
2) Fixed some linemode negotiation bugs.
3) Fixed Telnet options printing on screen.
4) 'More' command fixed in FTP.
5) rsh utility added.
6) FTP color bug fixed.
7) 8-bit output mapping now allowed.
8) Mouse support added for editing. Currently, the movements are mapped to the
arrow keys, the left button is mapped to '\n', and the right button is
mapped to 'ScrlLck'.
9) Disable/enable mouse support (8). The mouse is disabled by default-
pressing "Alt-M" or clicking the right mouse button enables it. Pressing
"Alt-M" or the right mouse button again disables it, etc. Note that
clicking the right mouse button to enable/disable the mouse also
enables/disables scrollback mode. This means you can do a scrollback
without touching the keyboard.
10) THE MESSAGES SCREEN IS NOW ALT-Z, _NOT_ ALT-M!!
11) MGET in ftp now checks filenames for dos compatability TO SOME EXTENT.
12) SITE command support added to ftpbin.
13) DEPCA driver should be fixed now.
14) MGET and MPUT now ask (Yes/No/All/Quit) for each file. All gets all the
remaining files without interactive prompting, Quit terminates the
current batch.
BUGS FIXES FOR NCSA Telnet 2.3b13:
1) 3c505 driver added to release. Use in the standard manner for hardware
boards.
2) BICC driver added to release. Use in the standard manner for hardware
boards.
3) Bugs with the ftp server in telnet & the standalone ftp client/server
should be fixed. This should prevent them from locking up at random
times.
4) 'More' command added to the standalone ftp client/server, to toggle the
state of it, type "more" at the command line. This should help with
the lines scrolling off of the top of the screen.
5) Standalone ftp client/server now uses the colors set in the config.tel
file.
Known Bugs: Please see the BUGS file in this directory.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) A VGA monochrome screen driver.
3) Overlaying the code so that Telnet will take up less memory.
4) Maybe update the telpass interface.
5) Enhance the vt110 emulator to support double width & double height
characters, and the printer toggle switches.
Please keep the bug reports coming in.
pctelbug@ncsa.uiuc.edu
BUG FIXES FOR NCSA Telnet 2.3b12:
1) The problem with the backspace acting like a carriage return in ftpbin
has been resolved.
2) FTP now handles disk full errors correctly, and also intelligently
strips off the ^Z character on the end of text files which have it.
3) The Appletalk driver is now working. You need to specify the interupt
that the appletalk card is using in the config.tel file, i.e.:
hardware=atalk
interrupt=60
4) Output mapping has been added to allow foreign character sets to display
better. The format is very similar to the keyboard mapping, i.e.:
"set key a b" in the output mapping file would map all the 'a' characters
displayed onto the screen to 'b' characters when the are displayed.
This output mapping is specific to each session and may be turned on
and off from the parameter menu (Alt-P). The entry to the config.tel
file is as follows:
outputfile=<filename>
5) Sometimes characters from teh extended keyboard are getting eaten.
These include the '5' key on the numeric keypad, and the f11 & f12 keys.
This can be solved by turning off the clock display. A menu option
has been added to the parameter menu (Alt-P) to facilitate this.
6) The BOOTP method of receiving an ethernet address has been fixed and
is now fully functional. Please note that some of the utilities
we provide may not work correctly with this option, for example,
all the hosts which can print on a UNIX host are usually indexed by
their IP number, which in the case of BOOTP is dynamically assigned.
This will mean that you will probably not be allowed to print on the
UNIX machine.
7) Removed the check for the '-h' being the first parameter for LPR to
specify the config.tel file, as it was causing more problems than
it was solving.
8) Cleaned up some problems with the graphics menu (Alt-G) hanging the machine
when tektronix mode was not initialized.
9) Included the object files for the assembly files for those people without
assemblers.
10) Included makefiles for Microsoft C 6.0 and Turbo C. (makefile.msc &
makefile.tcc respectively)
Known Bugs: Please see the BUGS file in this directory.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) A VGA monochrome screen driver.
3) Overlaying the code so that Telnet will take up less memory.
4) Maybe update the telpass interface.
5) Enhance the vt110 emulator to support double width & double height
characters, and the printer toggle switches.

pctelbug@ncsa.uiuc.edu
BUG FIXES FOR NCSA Telnet 2.3b11:
1) Added support in config.tel for braodcast IP address to be set, this
allows for better compatibility with out-of-date networks which use
different broadcast IP numbers. To use this option, include the line:
broadcast=xx.xx.xx.xx # where xx.xx.xx.xx is the broadcast IP number
for the network you are on.
2) Fixed the parsing of the keyboard mapping file to accept mixed case
strings, and octal & hex strings.
3) Changed the Abort Telnet Key to Ctrl-Shift-F3.
4) Fixed the memory overwrite problems when changing the session name
and the capture file name.
5) Fixed the problem with the backspace in ftpbin not working correctly.
6) Fixed problem with Ctrl-Home & Home crashing the machine when
tek=no was in the config.tel file.
7) Added support for thr DECnet DEPCA ethernet boards, this hardware option
is:
hardware=decnet # DECnet DEPCA boards
8) Fixed assorted memory bugs associated with the ftp server in telnet.
9) Added the ability to shell to DOS while in server mode, with the ALT-E
option.
10) Added the option to capture the screen to a file, with the ALT-D command.
11) Added the following network utilities:
finger - same as the UNIX command finger
rexec - same as the UNIX command rexec, except it doesn't allow for
interactive input from the user on the PC.
setclock - set the PC clock from a UNIX machine.
12) Fixed the mouse driver begin backwards in scroll back mode.
13) Added more characters for the password in ftpbin to be transmitted.
14) Added support for the ACCT command in ftpbin.
15) Added an option to ftpbin, -e <filename>, which accepts scripting input
from the file: <filename>, but is un-scripted for the user name and
the password.
16) Fixed ascii transfer in ftpbin, to not drop the last character, or
append ctrl-m ctrl-[, in certain cases.
17) The appletalk driver should be working, give it a try.
18) Please note the bug report address is changed from telbug@ncsa.uiuc.edu
to pctelbug@ncsa.uiuc.edu.
19) Somebody e-mail me, if they actually get a NULL pointer overwritten
error when exitting from telnet, it may be fixed.
NOTE: For Microsoft Windows users out there, don't run Telnet in the
background, packets get dropped or written to other applications causing
crashes. Run Telnet in exclusive mode, and turn on bios screen usage
(bios=yes). We have also had conflicting reports of Telnet working well
with Windows, so at least try to take care.
Known Bugs:
1) Tektronix GIN mode is not fixed yet.
2) FTPBIN is slow, and doesn't handle disk full problems well yet,
and also has problems with small (~5kb) ascii files.
3) Pasting from the copy buffer into a session is not printed when in
line mode.
4) The keyboard drops f11, f12, and the keypad 5 key occasionally.
5) BOOTP is broken, to be fixed again in the next beta release.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) A VGA monochrome screen driver.
3) Overlaying the code so that Telnet will take up less memory.
4) Maybe update the telpass interface.
5) Enhance the vt110 emulator to support double width & double height
characters, and the printer toggle switches.
Please keep the bug reports coming in!
pctelbug@ncsa.uiuc.edu
BUG FIXES FOR NCSA Telnet 2.3b10:
1) Fixed LPR not to send a null length file when the file doesn't exist.
2) Grabbed another couple of interrupts to get the ctrl-c trapping better.
This should finally take care of the problem.
3) LPR now reads files from other drives correctly.
4) LPQ & LPRM now look for CONFIG.TEL environment variable, instead of
CONFIGTEL environment variable in order to be compatible with the
rest of the applications.
5) The packet driver interface now passes RARP packets. I am not totally
certain if it will pass a BOOTP packet or not.
6) A BRAND SPANKING NEW keyboard mapping interface. This facility should
be totally compatible with MS-Kermit keyboard mapping files. The only
thing we don't support are some of the kermit verbs to map to keys.
Please read the keymap.txt file for detailed information.
7) Moved a bunch of #includes around in the source to make porting to other
compilers easier.
8) Added a sane memory error trapping function. If telnet suddenly spits
a message at you about a memory problem and says that it has written
a telnet.err file, _PLEASE_ mail it back to us so we can fix the bug
which caused it. (For those of you who are interested in nice memory
debugging code, take a look at the memdebug.c file, it contains some
really slick replacements for dynamic memory allocation which I scarfed
from a recent Dr. Dobbs article and enhanced.)
9) Added the Alt+W command to send your password when ftp'ing back to your
own machine while in telnet. Just press Alt+W at the Password: prompt
and hit enter, your password from the telnet password file will be
sent back to your machine.
10) Patched the existing code some to enable the BOOTP support. To use this
method of recieving your IP number, just include the myip=BOOTP setting in
your config.tel file.
11) LPR was patched to print the burst page.
12) The color support has been enhanced to allow high intensity foreground
text and blinking backgrounds. To use this, just set whatever color,
nfcolor for example, to a color in capitals. For example, nfcolor=CYAN
would set the normal text's foreground color to bright cyan.
13) Because of the new keyboard mapping interface, the shifted function key
macros and the keyboard= entries in the config.tel were removed. Just
use the new keyboard mapping interface, its a lot better.
NOTE: For Microsoft Windows users out there, don't run Telnet in the
background, packets get dropped or written to other applications causing
crashes. Run Telnet in exclusive mode, and turn on bios screen usage
(bios=yes). We have also had conflicting reports of Telnet working well
with Windows, so at least try to take care.
Known Bugs:
1) Tektronix GIN mode is not fixed yet. (Sorry, but it will be one of the
first things I work on, I promise!)
2) FTPBIN is slow, and doesn't handle disk full problems well yet.
3) The dreaded NULL pointer error on exitting Telnet is still around. This
may not get fixed until we get the new version of Codeview, because Telnet
is too large to debug normally.
4) Pasting from the copy buffer into a session is not printed when in
line mode.
5) Mouse may move backwards in the scrollback for certain mice.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) Appletalk driver will get fixed.
3) Various people have asked for more screen drivers, so perhaps if a lot of
people ask for different screen drivers for tektronix plots, we will
add another screen driver or two.
4) Overlaying the code so that Telnet will take up less memory.
5) Maybe update the telpass interface.
Please keep the bug reports coming in!
pctelbug@ncsa.uiuc.edu
BUG FIXES FOR NCSA Telnet 2.3b9:
1) A patch was made to make the NIC PS/2 card work correctly.
2) The problems with the LPR utilities not having enough stack space has
been fixed.
3) The problem with domain name serving which was introduced in b8 has
been fixed.
4) Added an option to the config.tel file to determine whether the clock
should be on or off. The default is on
ex. - clock=off
5) Fixed several problems introduced in b8 having to do with the vt100
emulation. This caused various problems using EDT on Vaxes.
6) Fixed bug which did not reset the line wrapping mode when Alt-R was
pressed to reset vt100 emulation.
NOTE: For Microsoft Windows users out there, don't run Telnet in the
background, packets get dropped or written to other applications causing
crashes. Run Telnet in exclusive mode, and remember to turn off keyboard
re-mapping in your config.tel (keyboard=off), and turn on bios screen usage
(bios=yes). We have also had conflicting reports of Telnet working well
with Windows, so at least try to take care.
Known Bugs:
1) Tektronix GIN mode is not fixed yet.
2) The keyboard mapper still has a cruddy file interface, this will get
improved in the next couple of weeks.
3) The keyboard gets reset to a US keyboard from the users keyboard type.
4) FTPBIN is slow, and doesn't handle disk full problems well yet.
5) The dreaded NULL pointer error on exitting Telnet is still around. This
may not get fixed until we get the new version of Codeview, because Telnet
is too large to debug normally.
6) Macros and pasting the copy buffer are not printed when in line mode.
7) LPR sends a null length entry when a file doesn't exist.
8) Mouse may move backwards in the scrollback for certain mice.
9) LPR does not find files on other drives.
10) LPR may not be reading the command line for the -h option correctly.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) Definiteley re-write the keybaord mapping to handle arbitrary length
strings for any key on the keyboard.
3) Appletalk driver will get fixed.
4) Various people have asked for more screen drivers, so perhaps if a lot of
people ask for different screen drivers for tektronix plots, we will
add another screen driver or two.
5) Overlaying the code so that Telnet will take up less memory.
6) Maybe update the telpass interface.
This week, one of the developers for Telnet, Heeren Pathak, graduated from the
university and left NCSA to work at Mitre. I would like to thank Heeren for
all his effort and time he has devoted to this piece of software, and for
everyone to wish him well in his new endeavours.
Please keep the bug reports coming in!
pctelbug@ncsa.uiuc.edu
BUG FIXES FOR NCSA Telnet 2.3b8:
1) No change in the internal ethernet drivers. The Appletalk is still under
some work, but the ni9210 may be put on indefinite hold.
2) The previously reported 'bug' about Telnet corrupting the environment
when you are shelled out is a bug in the Microsoft compiler. There is
presently nothing we can do to fix this problem. Possibly when we get
our copy of Microsoft C 6.0 the problem will go away, but don't hold your
breath.
3) The scrollback has been speeded up and now also restores the screen
correctly when exitting. The cursor is now replaced correctly when you
exit. There are several new things about the scrollback buffer which
are documented here. The key sequence "home-home" will place the cursor
at the upper left corner of the present screen, and the key sequence
"end-end" will place the cursor at the lower right corner of the current
screen. Pressing "home" or "end" will take you to the beginning or end
of the current line respectively. "Pgup" and "Pgdn" move you an entire
screen up or down in the buffer, but don't move the cursor position.
The behavior of the scrollback buffer when the cursor is on the top or
bottom line and the up or down arrow (respectively) is pressed is now
determined by the "autoscroll=[no|yes]" configuration variable. If
autoscroll is yes (the default state), then the screen will continue to
scroll in a direction until the opposite key is pressed (i.e. the down
arrow, when scrolling up). If autoscrolling is off, then the buffer
will only scroll one line up further into the buffer.
4) Telnet now reports back negotiation information to the console window
about the option negotiation which is being processed with the telnet
server you are connected to. This allows you to see exactly what telnet
options are enabled and what the server would like Telnet to support.
5) The alt-B key now moves you a session back in the list of sessions you
have open. ( A source of great relief to me at least...)
6) A small vt100 bug was cleaned up which dealt with the "^[c" sequence
eating the next vt100 sequence which followed.
7) F11 & F12 are available as macro keys again (due to overwhelming response).
8) The keyboard mapping was eating the Print Screen key, but now it passes it
correctly, and prints out the text on the screen.
9) A new configuration option was added to allow sessions which are closed to
disappear without needing an additional keypress was added. This option
is "windowgoaway=[no|yes]" in the configuration file. The default state
is set to not make windows go away.
10) The following list of ftp commands was added to Telnet's ftp server:
CDUP - allows the ftp connection to change to the parent directory
MKD - allows the ftp connection to create a directory on the machine
running Telnet
RMD - allows the ftp connection to remove a directory on the machine
running Telnet
DELE - allows the ftp connection to delete a file on the machine
running Telnet
These last two commands violate the security of the machine running Telnet,
so we highly recommend that you create a password file for Telnet and use
it all the time. Without a password file, anyone can ftp to your machine
and wipe you out!
11) Linemode and Negotiate About Window Size (NAWS) options are added to
the telnet options that Telnet supports.
12) The ctrl-C is fixed for certain now! I patched the ctrl-C interupt
directly. The previous problems were caused by the Microsoft C compiler
doing odd things with the interupt signal.
13) Support for more function keys was added to the vt100 key support. This
is a non-standard addition, but several people asked for it. The function
keys F5 thru F10 now extended the F1-F4 vt100 sequences:
F1 - ESC[P
F2 - ESC[Q
F3 - ESC[R
F4 - ESC[S
F5 - ESC[T
F6 - ESC[U
F7 - ESC[V
F8 - ESC[W
F9 - ESC[X
F10- ESC[Y
14) Two additional options were added to the configuration file:
cursorstart=[0-9]
cursorend=[0-9]
These two options allow you to choose what line the cursor starts on
and ends on. These two options take a number, which is the number of
lines from the top of the character block to begin and end. The default
is to have an underline cursor in 24 line mode, and a block cursor in
43 & 50 line mode.
15) Support for the AT&T Starlan 10 ethernet board was added as an internal
driver. Thanks for Larry Hicks at Bradley University for the effort
in writing it. There is an example of the use in the config.tel
supplied with this package.
NOTE: For Microsoft Windows users out there, don't run Telnet in the
background, packets get dropped or written to other applications causing
crashes. Run Telnet in exclusive mode, and remember to turn off keyboard
re-mapping in your config.tel (keyboard=off), and turn on bios screen usage
(bios=yes). We have also had conflicting reports of Telnet working well
with Windows, so at least try to take care.
Known Bugs:
1) Tektronix GIN mode is not fixed yet.
2) The keyboard mapper still has a cruddy file interface, this will get
improved in the next couple of weeks.
3) The keyboard gets reset to a US keyboard from the users keyboard type.
4) LPR is crashing with a variety of errors.
5) FTPBIN is slow, and doesn't handle disk full problems well yet.
6) Domain look ups for long machine names have some problems.
(How long you say?, I don't know, I am still trying to get a grip on it).
7) The dreaded NULL pointer error on exitting Telnet is still around. This
may not get fixed until we get the new version of Codeview, because Telnet
is too large to debug normally.
Things Which Still Need To Be Crammed In:
1) All the bugs above.
2) Appletalk driver will get fixed.
3) Various people have asked for more screen drivers, so perhaps if a lot of
people ask for different screen drivers for tektronix plots, we will
add another screen driver or two.
4) Overlaying the code so that Telnet will take up less memory.
5) Maybe update the telpass interface.
This week, one of the developers for Telnet, Heeren Pathak, graduated from the
university and left NCSA to work at Mitre. I would like to thank Heeren for
all his effort and time he has devoted to this piece of software, and for
everyone to wish him well in his new endeavours.
Please keep the bug reports coming in!

BUG FIXES FOR NCSA Telnet 2.3b7:
1) No change in the internal ethernet drivers. The Appletalk is still under
some work, but the ni9210 may be put on indefinite hold.
2) The cursor changing from an underscore into a larger underscore on
monochrome monitors is rectified.
3) Ctrl-C will no longer break out of Telnet.
4) Added -r command line switch to turn output redirection off in ftpbin.exe.
5) Fixed various problems making "mget *" in ftpbin.exe do bad things to
memory and crash.
6) When shelling to DOS from Telnet, the COMSPEC= environment variable is
now checked to see what shell to spawn.
7) Undefined macro keys (shift f1-f10) no longer print wierd strings.
8) Hercules graphics mode fixed, now supports Tektronix mode again.
9) Patched ftpbin.exe so that the last character in a file (ctrl-Z) is not
omitted during binary file transfers.
10) Added function prototypes and #ifdef's to avoid header file re-inclusion
to source.
11) A couple of vt100 emulation bugs which only manifested themselves when
connected to a VMS machine have been patched, please check these out and
let us know if they are correct.
12) A bunch of bugs were found in various sections of the code which we believe
have eliminated the 'assignment to null pointer' run-time error when
exitting Telnet. If you experience this error please make certain to
report a bug and let us know about it.
13) SOURCE RELEASE!!! This is still a beta set of source. It has been cleaned
up well enough that it only generates a couple of "formal parameter not
used" warnings, but there is still some work which needs to get done.
NOTE: For Microsoft Windows users out there, don't run Telnet in the
background, packets get dropped or written to other applications causing
crashes. Run Telnet in exclusive mode, and remember to turn off keyboard
re-mapping in your config.tel (keyboard=off), and turn on bios screen usage
(bios=yes).
Known Bugs:
1) Tektronix GIN mode is not fixed yet.
2) The keyboard mapper still has a cruddy file interface, this will get
improved in the next couple of weeks.
3) The keyboard gets reset to a US keyboard from the users keyboard type.
4) When shelled out to DOS from Telnet, the environment is corrupted somehow,
but this is at the trailing end of the environment and doesn't cause
crashes (I think).
Things Which Still Need To Be Crammed In:
1) Telnet line mode support.
2) A few configuration options to allow users to change the cursor they use
in Telnet.

The ??? indicate boards that are buggy. Please test them out and report
back to us.
2) ftp shell escape fixed
3) ftp -h parameter correctly reconized
4) EGA tek emulator fixed
5) VGA tek support added
BIG FIXES FOR NCSA Telnet 2.3b5
1) 3c523 Driver fixed.
2) Additional keystrokes added to Scroll Lock mode
Home -> Beginning of Line
End -> End of Line
Cntl+PGUP -> Top of Scrollback buffer
Cntl+PGCN -> Bottom of Scrollback buffer
3) External TCP/IP Utilities
The following utilities now work with the new drivers and
keyboard mapper. If NCSA Telnet works these should also
work.
ftpbin.exe -> ftp client & server
minitel.exe -> a very simple telnet program
Network Printing Utilites contributed by Paul Hilchey.
lpr.exe, lpq.exe, lprm.exe.
4) 3c503 driver fixed.
The 3c503 board does not allow the software to determine whether
thin or thick Ethernet is being used. Therefore, telnet needs
to be told what type of wire is being used. A new config.tel
keyword "wire" has been added. Its usage is shown below.
wire=thin ; this is the default. Telnet will use thin Ether
wire=thick ; Telnet will use thick Ether
5) Keyboard Mapper bug fixes.
CAPS LOCK no longer blocks control and ALT characters.
NUM LOCK now maps the keypad correctly.
6) Keyboard Mapper addition. The keyboard mapper now addresses all the keys
on the 101 key (extended) keyboard. There is an extra map which has been
added to the already existing five keyboard maps (NORMAL, LEFT SHIFT, RIGHT
SHIFT, ALT, and CONTROL). The extra map is for the extended keys, these
keys are only generated by the extended keyboard. The extra map consists
of 89 pairs of integers (one for each key), and is in the same order as
the other maps (see the README file for details). The order of the maps
is now : NORMAL, LEFT SHIFT, RIGHT SHIFT, ALT, CONTROL, and EXTENDED.
7) ftp excepts full pathnames for changing directories. It requires that
you type a double backslash for each single backslash in the path name
however, i.e. "c:\\dos" for "c:\dos". You may use a forward slash '/'
for the backslashes in MS-DOS path names also, i.e. "c:/dos" for
"c:\dos".
8) Ungerman Bass PC/NIC driver is fixed.
9) Western Digital 8003A Microchannel Card fixed.
10) Drivers update
The following is an update on the status of the internal Telnet drivers.

The ??? indicate boards that are buggy. Please test them out and report
back to us.
2) Terminal type negotiation.
Telnet can now send its terminal type a host. The default terminal
type is "dec-vt100." It can be changed with the termtype option in the
config.tel file, e.g.
termtype="vt100"
will cause telnet to send the string "vt100" instead of "dec-vt100" to a host.
3) Telnet to "other port" works with Domain lookup
Previously, attempting to connect to a port on a machine requiring a
domain lookup resulted in a connection to the Telnet port and not the
specified port.
Now the sucessful lookup will result in the connection to the specified port.
BUG FIXES FOR NCSA Telnet 2.3b3:
1) Alt-E escape to DOS no longer results in stack overflow.
2) Addition of macros for shift-function key combination
(Shift-f1 through Shift-f12)
The shift-function key combinations can now be mapped to user-defined
strings. Twelve new keywords have been added to config.tel, one for
each function key (f1,f2,f3,....,f12).
To assign a macro string to a function key:
<key>=<string>
where <key> is one of the new keywords and <string> contains your
macro.
The following key sequences are used to generate special characters
in your macro. They follow the same style as the C programming
language and may seem strange if you are not familiar with C.
Desired Character Definition
----------------- ----------
Backslash (\) \\
TAB \t
CR LF \n or \r
Space \032
Number of text rows \#
Internet number of PC \i
The \xxx string, where xxx is a number between 0-255, will send that
character to the the host, e.g. the Space key above.
If your macro string contains spaces, then the string either
has to be encased in quotes or the space should be coded as
a special character.
e.g. f1="ftp \i\n" and f1=ftp\032\i\n are functionally identical.
BUG FIXES FOR NCSA Telnet 2.3b2:
1) Appletalk driver better (may not be quite right yet, but it is now
at least compiled into the executable correctly).
2) Client mode fixed from Microsoft C 5.1 port. Now works correctly
in binary mode.
