sms gprs gsm edge

[kalin m]

hi all...

just looking for a few pointers for setting up a sms gateway.
if somebody would like to share some knowledge on successfully 
implemented hardware (gprs/gsm/edge modems/drivers) and software like 
kannel, smstools, etc...

for example i just talked to a salesperson at a company called moxa 
(http://www.moxa.com/product/oncell_g3100.htm) and was looking at their 
g3100 model gprs modem. according to their own specifications they have 
freebsd drivers. anybody has had any experience with those?!

any information will be appreciated.. 

thank you....
