How to receive/send data from/to TCP connection

[vannut]

After you established a connection with attachGPRS() and you've connected with connectTCP you'll have to write over the gsm-serial connection. Assuming your connection is stored in gsm:

//- at first sent the command to initiate the 'line'
    gsm.SimpleWriteln("AT+CIPSEND");
//- wait for a proper response
   if(gsm.WaitResp(2000,50,">")== RX_FINISHED_STR_RECV){
      //- write your data to the server:
           gsm.SimpleWriteln("Some data here");
      //- end with this end sequence to terminate the session
      //   don't know for sure what it does/means but I found this by trial and 
      // error. So maybe somebody else could enlighten us ;)
          inSerial[0]=0x1a;
          inSerial[1]='\0';
          gsm.SimpleWriteln(inSerial);
   }
