  24. // The Program runs on the PC side and uses Win32 API to communicate with the serial port or //

  26. //----------------------------------------------------------------------------------------------------//
  27. // Program runs on the PC side (Windows) and transmits a single character. //
  28. // Program uses CreateFile() function to open a connection serial port(COMxx). //
  29. // Program then sets the parameters of Serial Comm like Baudrate,Parity,Stop bits in the DCB struct. //
  30. // After setting the Time outs,the Program writes a character to COMxx using WriteFile(). //
