Yes all CDS modems can use an AT command to log onto the internet in TCP or UDP mode by using AT-Commands. 

These commands work when the modem is standard mode waiting for an inbound circuit switch call.

The following commands will log you onto to the 1x system.

AT+TCP=166.166.166.139,PORT,TIME you will see a connect message – if your using Modem Emulation.

CONNECT  IP = 166.139.99.93

Example:  AT+TCP=166.139.89.79,2000,5    Client mode\unit connecting first"

Example:  AT+TCP=166.139.89.79,L2000,5   "Server mode\Listen in mode"

L = Server mode \ listen mode   “No L remote is in Client mode”

2000 = Port

5 = stay log on for 5 minutes  “Time refresh after every packet”

Make sure you have your User name and password program in 1x setup menu
