/*
* DEC 93 Erik Bos <erik@xs4all.nl>
*
* Copyright 1996 Marcus Meissner
* FIXME: use HFILEs instead of unixfds
* the win32 functions here get HFILEs already.
*
* 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]
* I only quick-fixed an error for the output buffers. The thing is this: if a
* WinApp starts using serial ports, it calls OpenComm, asking it to open two
* buffers, cbInQueue and cbOutQueue size, to hold data to/from the serial
* ports. Wine OpenComm only returns "OK". Now the kernel buffer size for
* serial communication is only 4096 bytes large. Error: (App asks for
* a 104,000 bytes size buffer, Wine returns "OK", App asks "How many char's
* are in the buffer", Wine returns "4000" and App thinks "OK, another
* 100,000 chars left, good!")
* The solution below is a bad but working quickfix for the transmit buffer:
* the cbInQueue is saved in a variable; when the program asks how many chars
* there are in the buffer, GetCommError returns # in buffer PLUS
* the additional (cbOutQeueu - 4096), which leaves the application thinking
* "wow, almost full".
* Sorry for the rather chatty explanation - but I think comm.c needs to be
* redefined with real working buffers make it work; maybe these comments are
* of help.
* 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.
