//  Written by  Joseph Goldburg  mobile  61 412 750 765  email  joe.g@optusnet.com.au<br />
// <br />
//  Version 0.1  beta only<br />
//<br />
//<br />
//  This Program takes a input text file GSM  AT commands and send them to the serial port<br />
//  command line options  are<br />
//<br />
// ConsoleApplication1  COMx  INPUT_FILE  LOG_FILE  PAUSE<br />
// Where<br />
//      COMx   is COM1 COM2 COM3 serial port etc<br />
//<br />
//      INPUT_FILE is the input AT text file name  file name but be 8.3 dos file format<br />
//<br />
//      LOG_FILE  text file for the log output file name must be 8.3 dos file format<br />
//<br />
//      PAUSE if any character  then the program will wait until keypress to exit<br />
//<br />
// Example calling the command line <br />
//<br />
//            ConsoleApplication1  COM1 AT.txt log.txt<br />
//<br />
// Example of INPUT_FILE  AT.txt  for sending SMS's<br />
//<br />
//      AT+CMGS="61412750765"<br />
//      Sending text messages is easy^z<br />
//      AT+CMGS="61412750765"<br />
//      Sending another SMS message^z<br />
//      AT+CMGS="61412750765"<br />
//      Yet another text message^z<br />
//      ATZ<br />
//<br />
// Any AT commands can be sent, jst add them to the text file<br />
//<br />
// Special consideration is given to ascii characters "^Z"  or "^z" these are turned in to ascii control characters<br />
// Baud rate fixed at 115200<br />
