What, exactly, is the error message? 

If your app claims the port is busy it could be either an access
permission problem or that some other program is using it. setserial
reports "Device or resource busy" if the device is in use and "No such
file or directory" if the device file doesn't exist.  It may be worth
running this dual command:

	ls -l /dev/ttyS*; sudo lsof | grep 'ttyS.'

immediately before and after trying your Wine app.
