The names follow an irregular pattern (not like Linux, where it's a very regular pattern): the one you want starts with "tty." followed by some string describing the device providing the serial port. Make a symlink from that device file to dosdevices/com1 in your Wine prefix (usually it's ~/.wine, where '~' is your home folder). By the way, you can't even see the .wine folder from the Finder, much less make a symlink in it. You have to use the command line. Open Terminal (in /Applications/Utilities) and type this in: ln -s /dev/tty.<whatever> ~/.wine/dosdevices/com1 followed by Return. Replace '<whatever>' with whatever's after the "tty." in the device file. Then try your program again; maybe this time it will work. Chip
