COM – Serial Interface 4.4
54
Outgoing and incoming calls can be made during GPRS connection. The GPRS
connection remains active during the whole call but no data can be transmitted
(EasyGate is a GPRS terminal of class B). Once the call is terminated, data
transmission is recovered immediately.
List of Supported AT Commands
There are original files related to SIEMENS GSM modules in the PDF format on the
EasyGate CD-ROM.
Caution
Since the GSM module is primarily used by the EasyGate central processor
for voice calls, use AT commands carefully. You might misconfigure the
GSM module thus making EasyGate inoperative. To solve most of these
problems, switch EasyGate off and on again to make the central processor
execute full initialization of the GSM module.
