The "recent changes" table at the standard compendium of modem info for
Linux (at URL http://www.o2.net/~gromitkc/winmodem.html) lists the "SupraMax
56K PCI, Model 2260/2370, SM56IPC-XL1, Rockwell chipset" as an HSP modem
("Winmodem") that willl not work with Linux. 

The main table at the same site lists two other 2 "SupraMax 56K PCI" modems
with different modem numbers. Status of both is "unknown" with respect to
Linux compatability. I'd *guess* that they won't work, based on the fact
that ALL PCI modems (with possibly one exception; see above URL for details)
are HSP modems and do not work with Linux.

That said, here are some things you can check to try to decide if your new
modem will work with Linux:

1. Does the "system compatibility" list on the box mention it working with
either WIn 3.1 or DOS? If so, it WILL work with Linux. Usually, a modem that
will work ONLY with Win95/98/NT will NOT work with Linux.

2. If you put it in your system, does Linux detect it (as a serial port)
during the boot process?

3. If you know what device it is on, can you detect it with setserial? (That
is, if you run "setserial /dev/ttyS?", replacing ? with the appropriate
number, does the return info include a UART type)? 

One more thing: this is not a kernel issue but a driver issue. There are no
drivers in existence or being actively worked on to make any HSP modems work
under any version of Linux. Someone else recently posted the name of a site
(www.linmodem.org, I think) that runs a discussion list on HSP driver
development, but that effort looks to be at too early a stage for us to know
if it will succeed.
