# verify-be-serial.sh - both-directions RS-232 gate for the Be API ports.
|
|
#
|
|
# Runs SERTEST (examples/sertest: banner, then echo) in the port's VM
|
|
# (scripts/lib/beGate.sh) with the machine's second serial port joined to
|
|
# the host peer (scripts/lib/serialLoopPeer.py) over TCP: the peer listens,
|
|
# QEMU's COM2 connects to it, and JOEYLIB_SERIAL names COM2's device to the
|
|
# program (Haiku's /dev/ports/pc_serial1; COM1 is the VM's console). The
|
|
# peer waits for the banner, sends a probe and expects it echoed, so the
|
|
# chain is JoeyLib's POSIX serial HAL (src/hosted/posix) -> the system's
|
|
# termios -> its serial driver -> QEMU -> the host. QEMU's TCP serial carries no modem lines: DTR and the close's
|
|
# settings are gated on SDL3 (verify-sdl3-serial.sh).
|
|
#
|
|
# BeOS R5 SKIPs: its serial driver finds the ports through the ISA plug and
|
|
# play bus, which the VM goes without (installer/lib/beos.sh: it crashes R5
|
|
# in the fail-safe video mode), so the machine has none.
|
|
#
|
|
# Usage: scripts/verify-be-serial.sh [haiku|haiku32|beos]
|
|
# Requires: the port's VM (component haikuVm, haikuVm32 or beosVm), python3;
|
|
# build/PORT/bin/SERTEST (make PORT).
