Hi All,

I'm currently testing a SIM800L GSM module and have no probelm at all to make it work via my 18f2431 PIC.

So, what's the problem?

In fact, I want to make this module work also via the Serial Comunicator from Mecanique but this seems just not possible.

Here is an example of a SMS message I want to send:

working with PIC: SEROUT PORTB.4,2,["AT+CMGS=",34,"+4179xxxxxx",34,10,"Hello Roger",26,10,13]

not working with serial com: "AT+CMGS="+4179xxxxxxx",10,"Hello Roger",26

Going back to basics, when I send a simple AT command and set the Serial Communicator to add a CR terminator, it will work.

If I select "no terminator" and try it like this AT,13 , nothing will happen.

How is the CR generated in the Serial Communicator? Does anyone know?
