It's possible to buy bare  cell modems and dev boards to interface to their
usually obscure and  microscopic connectors, but they're annoyingly 
expensive.
I have some C  code I wrote to do this for ARM (bare, without operating 
system)
connected  to a crappy Telit GSM modem. It works fine, but could probably 
be refined  quite a bit. I'm happy to provide it though it would require 
modification  for other brands/models of cell modem, I'm sure. I used this
for SMS  to/from teletype loop for a while before switching to  HeavyMetal.

Currently I have Google Voice forward SMS messages to an  email address and
a linux box collects the email and parses/formats it for  the teletype and
hands it off to the loop via HeavyMetal. I hope that will  continue to work.
