They should look just like a modem. (Hook the cable from serial port
to the phone) You may have to set your serial-port speed to something
slower than you are used to, like 19200 or 38400, but from there, these
things are designed to act just like any POTS modem.
There are 3 types of data-services:
async-data (dial atdt555-1212) to connect to another modem.
packet-data (dial atdt#777 or start PPP) to connect via ppp using them as an ISP.
(the phone itself acts as a "forwarding ppp interface" transparent
to the local ppp client program)
cellular-modems (a pcmcia card, looking like a modemm, connecting to the phone)
(you can add things like v.42bis and special error-correcting and
link-speed negotiation features more easily to a pcmcia card)
Most companies developing these products build them for compatibility of
popular OS's.
...this would [unfortunately] be: Microsoft products, Linux, then *BSD.
These services have been in development for quite some time, consumer demand
has not been there to justify an earlier rollout, If you happen to stumble
across a product that is not compatible, I'm sure the manufacturer will be
quick to resolve it.
