The VSC modem is a "Winmodem", meaning that it will only work in Windows
95. It is not really a modem, but rather a bridge between the computer's
CPU and the phone line. All modem functions are emulated in software
that cannot be reproduced in Linux due to technical, legal, and m*

Linux requires a standard serial modem.


1. Help: Modem doesn't work -- Compaq Presario 336-VSC Modem

I'm using a Compaq Presario 336-VSC Modem which works very well under
Win95. But it seemed that linux can't recognize it at all. When I run
kermit, I got an error message as follows,

C-Kermit> set line /dev/cua1
C-Kermit> /dev/cua1 is not a terminal device
C-Kermit> sorry, can't open connection to /dev/cua1

When I am trying setserial -a /dev/ttyS1, the irq(3) and port(0x02f8)
are ok but uart is UNKNOWN.

It's a fax-modem connected to COM2 and thus the device name should be
/dev/cua1 and /dev/ttyS1.

Could you please give me any idea about what is going wrong? Do I need
a special device driver?
