Hi, I'm using a software called 'remserial' to access a remote serial port. The program creates a pseudo tty in /dev (/dev/pts/0). I can access the port with another applications, but not with WINE. I read that WINE uses 'setserial' to grab information on the port. If so, that's the problem. AFAIK setserial doesn't work with pseudo tty: bash-3.1# setserial /dev/pts/3 Cannot get serial info: Invalid argument That's probably why i keep getting EscapeCommFunction() == FALSE! errors. :-( Searching the list i found a very old patch maded by Scott W Gifford: http://www.mail-archive.com/wine-devel%40winehq.org/msg07055.html and some others by Eric Pouech, but none seens to work. Any help would be appreciated. TIA Ricard Moura NCS Sistemas Inteligentes
