Both now do what the firmware does, at the device level so the shared
PlasmaCanvas (and vRIO's embedded glass) are untouched:
- Jumper 4 → display orientation. VPlasmaDevice gains a PlasmaOrientation
property; in Vertical the logical space is 32x128 and every dot is rotated
onto the physical 128x32 glass via a new Plot() helper that all drawing
(text, cursor, ESC P graphics, ESC Q/R bounds) now goes through. Jumper 4
installed = horizontal (the normal cockpit setup, default), removed =
vertical. Changing it re-inits the panel, like the boot strap read.
- Jumper 5 → ShowTestPattern(): lights every dot (the power-on dead-dot
check the firmware runs at $B888). Removing the jumper clears it.
The config panel wires both up and shows the live orientation in the
counters. 27 unit tests pass (3 new: vertical rotation mapping, orientation
re-init, test pattern), including the unchanged horizontal path.

Replaces the guessed font/cursor model with what the firmware dump proved:
- The 8 real Babcock ROM fonts, extracted from tms27pc512.BIN into
PlasmaFonts.cs (6x8, 6x10, 7x10, 12x16, 12x20). Drops the public-domain
5x7 stand-in and PlasmaFont.cs.
- Pixel-addressed cursor with the real positioning commands: ESC Q (row Y,
0-31) and ESC R (column X, 0-127), matching the firmware's range checks.
Cursor motion (BS/HT/LF/VT/CR) now moves by font pixels, not cells.
- ESC K selects fonts 0-7 (out-of-range ignored, per firmware); ESC H
attributes are the low 4 bits (half/underline/reverse/flash).
Deferred (documented in FIRMWARE.md): the 10 double-buffered pages
(ESC I/i) and vector-graphics primitives (ESC A-F); vPLASMA keeps a
single-page model for now.
Verified: 24 unit tests pass; the three self-test pages render the real
glyphs (big font 4 banner, full charset in font 0, graphics). Next: begin
the modern-parts hardware replica, with this as the reference firmware.

The cockpit's second serial device joins vRIO: the 128x32 dot-matrix
plasma on COM2 (9600 8N1) that the game draws mission text and status
graphics on. VPlasma.App opens the device end of a COM port, decodes
the display's command stream, and renders the matrix in plasma orange.
The command set is recovered from two Tesla 4.10 artifacts: the game's
driver (L4PLASMA.CPP — ESC P packed-bitmap row writes, ESC G 0 cursor
hide at boot) and the factory test tool PLASMA.EXE, whose data segment
pairs each command literal with its printf description (BS/HT/LF/VT/CR
motion, ESC @ clear, ESC L home, ESC G cursor, ESC K fonts, ESC H
attributes: intensity/underline/reverse/flash). Text renders through
the classic public-domain 5x7 set standing in for the lost ROM glyphs;
fonts 0-3 give 21x4 cells, fonts 4-7 the doubled 10x2. A Self test
cycles banner/charset/graphics pages through the same parser the wire
feeds, and the wire log shows every decoded command.
Verified end-to-end over the second com0com pair (host writing COM2,
vPLASMA listening on COM12). The verify skill gains the cross-process
combo-box lesson: string-carrying CB_* messages hang across processes,
so select ports by locally computed index via CB_SETCURSEL.
