But that doesn't look like a real option in this case, as he has a serial device (his external speech synthesizer) and an existing software (the utilities for said speech synthesizer) he is trying to run. As far as (Free)DOS is concerned, it can only provide assistance in form of DOS routines and info for the serial port that in turn rely on certain hardware info provided by the BIOS replacement of the VM. So it's up to the VM to handle this properly and it is my practical experience that most of them are likely to not properly provide that info, as most of them simply don't care about such "legacy" devices anymore...
