1 /*
2 * DEC 93 Erik Bos <erik@xs4all.nl>
3 *
4 * Copyright 1996 Marcus Meissner
5 *
6 * Mar 31, 1999. Ove Kåven <ovek@arcticnet.no>
7 * - Implemented buffers and EnableCommNotification.
8 *
9 * Apr 3, 1999. Lawson Whitney <lawson_whitney@juno.com>
10 * - Fixed the modem control part of EscapeCommFunction16.
11 *
12 * Mar 3, 1999. Ove Kåven <ovek@arcticnet.no>
13 * - Use port indices instead of unixfds for win16
14 * - Moved things around (separated win16 and win32 routines)
15 * - Added some hints on how to implement buffers and EnableCommNotification.
16 *
17 * May 26, 1997. Fixes and comments by Rick Richardson <rick@dgii.com> [RER]
18 * - ptr->fd wasn't getting cleared on close.
19 * - GetCommEventMask() and GetCommError() didn't do much of anything.
20 * IMHO, they are still wrong, but they at least implement the RXCHAR
21 * event and return I/O queue sizes, which makes the app I'm interested
22 * in (analog devices EZKIT DSP development system) work.
23 *
24 * August 12, 1997. Take a bash at SetCommEventMask - Lawson Whitney
25 * <lawson_whitney@juno.com>
26 * July 6, 1998. Fixes and comments by Valentijn Sessink
27 * <vsessink@ic.uva.nl> [V]
28 * Oktober 98, Rein Klazes [RHK]
29 * A program that wants to monitor the modem status line (RLSD/DCD) may
30 * poll the modem status register in the commMask structure. I update the bit
31 * in GetCommError, waiting for an implementation of communication events.
