Communications program (SuperVoice) and serial port modem (COM1 etc?)

[Andy Allen]

Hi,
I've installed (Windows program) SuperVoice 2.6 in Wine in order to use
a serial port modem (USR 56K Message Modem) for tel/fax message handling
(I've previously used it in Windows 2K). It seems to work OK up to a
point - trouble is I don't know how to get it to access the modem!
Probably a daft question, but how do I do that in linux (RH9)? - I'm
still thinking a bit in MS Windows terms! Grateful for any help,
Andy
