SMS Sending and Receiving
It is possible to send and receive SMS units using appropriate AT commands.
There are a number of PC programs that are based on this principle. Install SW
designed for SIEMENS GSM modules (SIEMENS mobile telephone SW can also be
used). You can send and receive SMS even during 2N® SmartGate voice calls.
Combination of COM Traffic with Voice Calls
As already mentioned, SMS transmission can be made even during telephone
calls. The SMS program is only blocked temporarily during outgoing call to GSM
establishing and incoming call from GSM ringing.
The same applies to PCManager monitoring. A message announcing that 2N®
SmartGate is blocked is displayed during voice call establishing.
No voice call to GSM can be made during CSD data transmission.
Outgoing and incoming calls even to GSM can be made during GPRS connection.
The GPRS connection remains active during the whole call to GSM but no data can
be transmitted (2N® SmartGate 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 2N® SmartGate CD-ROM.
Caution!
 Since the GSM module is primarily used by the 2N® SmartGate central
processor for voice calls, use AT commands carefully. You might configure
the GSM module wrong thus making 2N® SmartGate inoperative. To solve
most of these problems, switch 2N® SmartGate off and on again to make
the central processor execute full initialization of the GSM module.
