 I have successfully used 300, 1200, 2400bps modems over a device  
called the Motorola "Cellular Connection". This is a device which  
connects between the headset and tranciever of the cellular phone (  
just unplug the jack and place this little black box in the middle )  
and provides a RJ-11 jack for any compatible telco equipment. For my  
purpose I used a car phone, and also on a transportable (luggable!).

The modem I used was a Practical Peripherals battery operated  
mini-modem with no error correction.

The computers I tested was a Compaq LTE/286 (internal 2400 modem), a  
NEC Ultralite (internal 2400 modem), a Tandy MC-102(internal 300  
modem).

I found that the data was very reliable at rates up to 2400bps WHEN  
the car was not moving.
The data was usually garbled if the car was moving (use error  
correcting MNP modems to fix this).

I have some buddies at US WEST Cellular who have been installing the  
Cellular connection and
9600bps fax machines into their sales peoples cars to send copies of  
contracts back to the CSR's at the office, and they say they work  
GREAT!

If I remember correctly there are a couple of models available, the  
one I have is the "smart" jack. It allows normal modem operation like  
autodialing (you send a # to wakeup the cellular phone before the  
number, ie ATDT#1232323(RETURN)). The cheaper models require manually  
dialing the number from the handset, wait till you hear carrier then  
instruct your modem to go on-line. (ATO(RETURN)).

The Cellular Connection can be purchased and maybe leased from your  
cellular provider, or you can purchase one from Motorola. 

					Hope this helps!
