Hello Richard

TIOCGICOUNT is not the problem, it didn't work on wine 0.9.22 either. However
the error path taken in dlls/ntdll/serial.c from 0.9.23 when TIOCGICOUNT fails
is different, and the application takes a different code path and calls
IOCTL_SERIAL_CLR_DTR, which it doesn't seem to do in 0.9.22. My patch should
have fixed that, but you say it didn't help. Can you attach the output of:

WINEDEBUG='+comm' wine app.exe &> /tmp/log.txt

with my patch?

Also please post the output of:

strace -f -v wine app.exe &> /tmp/strace.txt

preferably both with a broken version, and with a working version of wine.
