I would like to write an application in Borland C++ Builder which can send and receive sms from a GSM module via AT commands. My GSM module is based on the Siemens MC35 GSM module. It is pluged over serial port (RS232) to the computer with GPS/GSM Evalation kit.
I have had a look in the internet and some forums but I could not find something useful.
Do you know any sources such as internet tutorials or good book where I can find information about it? I am mainly interested in how can I open a comport? What kind of data goes through (ASCII, binary)? How can I realise to send and receive the AT-Commands?
Thanks for your support
