Of course it is possible. "modbus frame " has nothing to do with "gsm frame ".

You open a channel and you can send any bytes trough two GSM modems. Don't care if it modbus or not.

The decoding is done by the final device.

Trere are many ways to open a channel between two GSM modems. It depends of the ammount of data, and the frequency you want to transmit them.

the Labview application genrate the mod bus frame formate , the data pass through Rs-232.my question is the labview application is can drive the gsm modem?

Of course it can. Use AT commands (with VISA Labview) to setup the modem (if needed) and to connect with the other GSM modem. Then Labview can start sending the data (modbus or not).

You can read the data at the other modem. Finally use AT commands to disconnect.

GSM modems-terminals have serial port. Like GM29. But Sony-Ericsson no longer exists. We manufacture GSM Modems-Terminals too. You can also buy the GSM Module itself, but you will neen a prinded circuit to have it connected with a PC.

Two GSM modems connect, like two mobiles phones are connected when you talk. Basic it is the same (the idea).
