[WMOD2 GSM modem with V120]

Thanks. Ultimately I just decided to send the AT commands using protocol send blocks which works well. Will need to get a more modern modem next time.

[WMOD2 GSM modem with V120]

I am trying to get a V120 to send an SMS message using a Wavecom WMOD2 modem but the port is never properly initialised. The error code is 2 (reply error). I have verified that the modem itself is working by sending SMS messages using Hyperterminal.

One thing that might be an issue is that there is no built-in configuration for this modem, so I had to make my own which may not be correct. Does anyone have experience using this modem? If so, which commands did you use to initialise it?

Should the PLC-side modem configuration just be the same as the port initialisation?

Thanks in advance.
