The RIO cockpit board now runs sustained sessions with button mashing; dropouts self-heal in ~1-3s. Documented in RIO-NOTES.md: - directserial RIO_TAP=<path> (host env): logs every TX/RX byte with host-us + emu-ms timestamps, plus config/RTS/DTR/break lines. This instrument found every root cause below. - Confs: rxburst:16 restored (no-burst reply pacing made the game ACK ~14ms late -> board dropped on the first long analog stream; the old 'rxburst corrupts boot' belief was the then-unpatched PCSPAK crash). priority=highest,highest (unfocused DOSBox was demoted and blew the ACK deadline). - BTL4OPT.EXE patch lineage (in ALPHA_1/, zip left pristine): v2 full DISABLE_AND_DIE NOPs (v1 left the IRQ/RTS-retract prologue live -> first protocol error deafened the driver), v3 TXMAXIDLE 4->32 (kills the button-press ACK-window livelock), v4 analog retry limit 15s->0.5s (dev value was 0.2s; recovery now near-instant). - Board firmware patch plan recorded for the EPROM-dump route.
