First you need to make sure that your GSM carrier supports CSD (mine 
doesn't AFAIK) and that it is activated on your account.

In the past people have mentioned that the Calypso performs similarly to 
an "Enfora Enabler" modem and there is some web-accessible documentation 
for that. The "AT+CBST" (select bearer service type) command seems to be 
involved.

There's probably some overlap between the CSD commands and the ones used 
for GPRS so I would also look at
