GSM/SMS - Huawei E3131
« on: February 23, 2015, 03:52:43 am »

I'm planning to put sending and receiving into my Delphi app.  I rather foolishly went out and bought a Huawei E3131 stick modem before looking for components to run it. 

I have tried to run the GSM demo and clicking on Open gives this error:-

Device "COM1" Open Error !!!
The system cannot find the file specified.

The log file says:-

[23/02/2015 3:24:00 p.m.] nrComm Lib v9.37 Pro  (TRIAL! Please register!)
[23/02/2015 3:24:00 p.m.] nrGsm: Queue finished

[23/02/2015 4:45:20 p.m.] Fatal Error: 1, 0, Device "COM1" Open Error !!!\0DhThe system cannot find the file specified
[23/02/2015 4:54:42 p.m.] nrGsm: Queue finished

I'm guessing that gsmdemo is not seeing the virtual serial ports.

Is the E3131 model supported by your software - I see in your list:-

"Huawei models: E220, E156G, E1550 and others"

Is E3131 an "other" or am I doing something wrong?

TnrGsm  component uses AT GSM commands (over serial port) for interactive GSM modem.
You need to check Huawei site and search correct drivers. And you will get several new
virtual serial ports in system.
