My Wine apps can use serial ports on the motherboard and on a 6-port serial adapter card but have never been able to see my pfranc USB-serial adapter. Other people have been able to use USB-serial adapters, so maybe the chipset in the adapter is important. On the other hand, all current Linuxes address serial ports as /dev/ttyS[0-9] and USB adapters as /dev/ttyUSB[0-9], so its equally possible that wine apps can't see USB devices because their names are different. Maybe OS X does something similar? Martin
