*
* History:
*
* Apr 3, 1999. Lawson Whitney <lawson_whitney@juno.com>
* - Fixed the modem control part of EscapeCommFunction16.
*
* Mar 31, 1999. Ove Kåven <ovek@arcticnet.no>
* - Implemented buffers and EnableCommNotification.
*
* 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.
*
* 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.
*
* July 6, 1998. Fixes and comments by Valentijn Sessink
* <vsessink@ic.uva.nl> [V]
*
* August 12, 1997. Take a bash at SetCommEventMask - Lawson Whitney
* <lawson_whitney@juno.com>
*
* 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.

* FIXME:
* The functionality of CommConfigDialogA, GetDefaultCommConfig and

* This is dependent on the type of COMM port, but since it is doubtful
* anybody will get around to implementing support for fancy serial
* ports in WINE, this is hardcoded for the time being. The name of
* this DLL should be stored in and read from the system registry in
* the hive HKEY_LOCAL_MACHINE, key
* System\\CurrentControlSet\\Services\\Class\\Ports\\????
* where ???? is the port number... that is determined by PNP
* The DLL should be loaded when the COMM port is opened, and closed
* when the COMM port is closed. - MJM 20 June 2000
