external modem

I've never needed to configure a modem w/ linux so I'm a bit lost.

I have a 56K creative (external) modem and I need to have it configured in KDE (KPPP) so it is *very* easy to use (in-laws' PC).

I have ppp support compiled into the kernel but when querying the modem in KDE's KPPP program it immediately tells me it can't find the modem, regardless of what devices I select and try. I compiled the ppp_generic driver as a module and I figured that would be all I'd need.

What can I do on a lower-level to verify that the modem is available? What else needs to be done?

Thanks!

You do not need low-level drivers or modules to get an external modem to work - it's on a simple serial interface.
If you plug it into COM1, then the modem will live at /dev/ttyS0, which is the first serial port.

You can set parameters for the port on the commandline by using setserial, but as you said, kppp should do all that for you too.

Do make sure to include kernel support for anything ppp related, since ppp communication uses quite a few of them.

What do you get if you try to initialise the modem by hand ?
If it is a sensible Hayes compatible one,
