Can now receive calls!!

I have been messing about with the TC35 GMS modem module and trying to get calls received.

According to the DOCs the word "RING" should be received when a call is received. Indeed I have experienced this when I was using the Nokia in the older version of Retro-Mobile.

I have literally spent hours trying to get a call received via the build in 9-D RS232 comms socket connected to my USB-COM port.

I was just about to order a new one on ebay, when I decided to try and use the headers on the module (which I had to solder on) and a max232 development board I bought to level-shift the output of the PIC.

It worked, must have a duff RS232 9-D socket or something!!

Anyway this makes it much easier and I can now develop the C code for the incoming call :)

NOTE:

The TxDo on the TC35 goes to the RxD on the MAX232 header.
Power is taken from the TC35 VDD to power the MAX232 module (5V ish).
GND on the TC35 has to be connected to GND.
It doesn't seem so important that the MAX232 module has its GND connected.
