Who owns /dev/ttyS0 and what permissions does it have? IOW, does the user where you're running the application have read and write access to the serial port. Please show us what "ls -l /dev/ttyS[0-3]" shows. What Linux distro are you using? If its an access permission problem, the information here may help: http://www.libelle-systems.com/free/wine/serial_port_access.html If you're comfortable adding UDEV rules that explains how to do it. If not, add the chmod command to /etc/rc.d/rc.local or wherever your distro puts local commands to be run at the end if the boot sequence. > > (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? > You can set them with the stty command.
