If I understood correct, is it possible then to make a Winmodem work under Linux by
the method you just described?
I have a Diamond SupraExpress i56 PCI internal modem... works Ok under NT, but not
Linux (still using my old external 14400 under it).
Also, NT doesn't let me view the COM3 port configuration. If I install Windows
95/98, and find out the correct values the modem is using, can I do setserial on the
COM port and expect Linux to use it Ok?
Actually this would be a real pain in the ass, because I'd install W95 just for
that, and immediatelly remove it from my computer.
Also, I'm a bit confused here about all this winmodem stuff. They're not PnP, right?
(pnpdump doesn't see it) So how do they set resources or rather let some OS set the
resources? Does every kind of these winmodems have a unique method (maybe
specific-driver-oriented) to set them?
Thanks,
Leo
