* 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.
|
|
*
|
|
* 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.
|

|
|
* 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.
