Hi Alex,

The first check I would do is to check if there is really something send over the serial line, e.g. with a serial line sniffer. Further check the parameters for the serial connection: baud rate, start, stop and data bits. This should be the same as what your modem is expecting.

I have not looked at the code yet. But that's the next step, especially if there is nothing going over the serial line and the serial parameters are correct.

Regards,
Jan
