umass should certainly not be needed for a modem to work, it is for
hard disks and the like.

What probably is needed on the other hand is umodem(4) and/or ucom(4). 
I do not belive they are included in a GENERIC kernel so you might not
have those modules loaded.

If you have not already tried it make sure those modules are loaded
and see if your modem attaches to umodem.

IF you have a classic RS-232 serial port that is supported then any
external modem that connects via RS-232 should work. 

As for what serial ports work is another question. Just about all of
those built-in on motherboards should work, but unfortunately many
modern motherboards do not include serial ports any longer.
Expansion cards (PCI or PCI-E) may or may not work depending on exactly
what chips are used on the cards.  (If that use classic 16550A chips
(or a good copy thereof) chances are excellent that it will work. If
they use more modern (and more powerful) chips the chances are not
quite so excellent.)


(As for promises about what *will* 100% guaranteed work, which seems to
be what you really want, I am afraid I can't give any.  It has been
several years since I last used a dialup modem, so I don't know for
sure what *will* work with todays software, only what should work.)
