/*
* DEC 93 Erik Bos <erik@xs4all.nl>
*
* Copyright 1996 Marcus Meissner
*
* Mar 31, 1999. Ove Kåven <ovek@arcticnet.no>
* - Implemented buffers and EnableCommNotification.
*
* Apr 3, 1999. Lawson Whitney <lawson_whitney@juno.com>
* - Fixed the modem control part of EscapeCommFunction16.
*
* Mar 3, 1999. Ove Kåven <ovek@arcticnet.no>
* - Use port indices instead of unixfds for win16
* - Moved things around (separated win16 and win32 routines)
* - Added some hints on how to implement buffers and EnableCommNotification.
*
* May 26, 1997. Fixes and comments by Rick Richardson <rick@dgii.com> [RER]
* - ptr->fd wasn't getting cleared on close.
* - GetCommEventMask() and GetCommError() didn't do much of anything.
* IMHO, they are still wrong, but they at least implement the RXCHAR
* event and return I/O queue sizes, which makes the app I'm interested
* in (analog devices EZKIT DSP development system) work.
*
* August 12, 1997. Take a bash at SetCommEventMask - Lawson Whitney
* <lawson_whitney@juno.com>
* July 6, 1998. Fixes and comments by Valentijn Sessink
* <vsessink@ic.uva.nl> [V]
* Oktober 98, Rein Klazes [RHK]
* A program that wants to monitor the modem status line (RLSD/DCD) may
* poll the modem status register in the commMask structure. I update the bit
* in GetCommError, waiting for an implementation of communication events.
