==== Example ====

{{{
   if(commTypeSelection == SERIAL)
   {
      int commPort = 2;
      CCommSerial *pSerial = new CCommSerial(commPort);
      pComm = pSerial;
   }
   pComm->Open();

   // Now the app can call pComm->Send to send data without regard for whether it is serial or TCP/IP.

   pComm->AddRcvEvent(CHR_STX, CHR_ETX, CommEventDataMsg, 0, NULL);

}

void StopCommunications(void)
{ 
   if(pComm != NULL)

       time_t tmval;
       time(&tmval);  // Get timeval

       char response[12];
       sprintf(response, "%d\n", tmval);
       // pConnection isn't important in the case of serial port, but if TCP/IP server it is important to send
       // the response to the connection that the message was received from.
       pComm->Send(pConnection, response, strlen(response);
