Concat a Char to String.

Yeah my bad... My reason code explains it all.

STX = Start Of Text:

aka CTRL-B

Code:

---

                cMsgFinal = malloc(iLen + 4);

                if(cMsgFinal)
                {
                        cMsgFinal[0] = cSTX; 
                        cMsgFinal[1] = 0;
                        strcat(cMsgFinal, pMsg);
                        strcat (cMsgFinal, "\r\n");
                        VcomSendSocket(iUserSocket, cMsgFinal, iLen+4);
                        free(cMsgFinal);
                }
                else
                {
                      // Do some error for out of memory situation!
                }

The blue bit is something I'm not sure of - I suspect you want to send ALL of the message, not all but the last 4 [but perhaps it's adding 4 somewhere else?]

The red bits I'm pretty darn sure are right.
