  20  * History:
  21  *
  22  * Apr 3, 1999.  Lawson Whitney <lawson_whitney@juno.com>
  23  * - Fixed the modem control part of EscapeCommFunction16.
  24  *
  25  * Mar 31, 1999. Ove Kåven <ovek@arcticnet.no>
  26  * - Implemented buffers and EnableCommNotification.
  27  *
  28  * Mar 3, 1999. Ove Kåven <ovek@arcticnet.no>
  29  * - Use port indices instead of unixfds for win16
  30  * - Moved things around (separated win16 and win32 routines)
  31  * - Added some hints on how to implement buffers and EnableCommNotification.
  32  *
  33  * Oktober 98, Rein Klazes [RHK]
  34  * A program that wants to monitor the modem status line (RLSD/DCD) may
  35  * poll the modem status register in the commMask structure. I update the bit
  36  * in GetCommError, waiting for an implementation of communication events.
  37  *
  38  * July 6, 1998. Fixes and comments by Valentijn Sessink
  39  *                                     <vsessink@ic.uva.nl> [V]
  40  *
  41  * August 12, 1997.  Take a bash at SetCommEventMask - Lawson Whitney
  42  *                                     <lawson_whitney@juno.com>
  43  *
  44  * May 26, 1997.  Fixes and comments by Rick Richardson <rick@dgii.com> [RER]
  45  * - ptr->fd wasn't getting cleared on close.
  46  * - GetCommEventMask() and GetCommError() didn't do much of anything.
  47  *   IMHO, they are still wrong, but they at least implement the RXCHAR
  48  *   event and return I/O queue sizes, which makes the app I'm interested
  49  *   in (analog devices EZKIT DSP development system) work.
