But USB->serial dongles ARE already supported in wine! The catch is that you have to add a link manually. Since I just had to do it again (under Crossover) for a certain piece of software that communicates over serial to program a radio, I can tell you from memory it involves simply making a link in the "dosdevices" directory from your serial port to the com port. In my case, I did the following: ln -s /dev/ttyUSB0 ./com1 where /dev/ttyUSB0 is my USB -> RS-232 dongle and "." is wherever your "dosdevices" directory is (somewhere under .wine or, for Crossover Linux, .cxoffice/<bottle>); also, the exact location and name of the serial device may be different (for instance, I believe ACM modems are named ttyACMx, but I don't remember for sure), so you need to look, but it's really as simple as this as far as wine is concerned.
