Hello, I've got RFID card reader plugged in serial port. cat /dev/ttyS0 ...gives me ID of the card I'm using => that's OK As soon as I open the port with win32 appication via wine... I get no data from reader. Even cat /dev/ttyS0 does not work anymore afterwards. I thinks it's because as soon as application opens it via wine some tty flags change: (PS: Of course I created symlinks in .wine/dosdevices/com[1-4] -> /dev/ttyS[0-3] )it changes some flags: min=1 -> min=0 -hupcl -> hupcl -ignbrk -> ignbrk icrnl -> -icrnl ixon -> -ixon opost -> -opost isig -> -isig icanon -> -icanon iexten -> -exten echo -> -echo -noflsh -> noflsh Is it possible to tell wine to not change any flags or set them on my own?
