I can't be sure, Peter, but my hunch is that you are looking in the
wrong place. I'm assuming the modem is attached to a serial port and is
not one of those pseudo-modems that requires a special module (If I'm
wrong, then you really left out important info) in what follows.
Serial port support is all but always compiled into kernels, not added
as modules. (And I don't see anything that looks like a serial-port
module in either of the lists you sent us, in any case.) But setting up
serial ports so they actually work requires running "setserial" with
appropriate values.
I'd suggest you approach this by:
(a) Finding out what /dev/modem is a symlink to
(b) Running setserial on that device (e.g., "setserial /dev/ttyS0") to
see what settings are present.
If they are different between Slackware and Fedora, that points to your
problem. If you can't spot it yourself, post here the COMPLETE results
of this testing and probably someone can help you spot it.
You might also check the init-script sructures of the two distros to see
where and how (and even if) both run setserial.

Suddenly I cannot access my modem.
Minicom will just stay offline.
efax version 0.9

Giving command: fax receive
I get:

efax: 37:31 done, returning 2 (unrecoverable error)
There were errors (see 0717143714.log).
I tried it with kernel 2.4.31, it will not work either.
I moved over to Fedora4, same machine, same HD. Minicom is on-line and dials
and pppd dialing is working as well, meaning there is nothing wrong with the
hardware.
Here is the output of lsmod in Fed4 w/o the snd_ bits:

Where could be the hitch that the modem is not responding in slackware?
Thanks for any help!
