SetCommState( cDCB )-> <lSuccess>
------------------------------------------------------------------------------


 PARAMETER:

  <cDCB>    Is a string containing a DCB ( Device Control block ) structure. 
            The DCB structure is created by using BuildCommDcb()


 RETURNS:

  <lSuccess> is TRUE if the function is successful



 DESCRIPTION:

  SetCommState() sets a communications device to the state specified by a
  device control block. This function reinitializes all hardware and
  controls as defined by the DCB structure, but it does not empty the
  transmission or receiving buffers. 
  Look up SAMPLES\TestComm.prg for a working communication sample
