I have a custom application I am trying to write
that needs to communicate over modem to a remote
computer. The "TTY" source distributed with the
3.0 SDK loses characters even at _2400_ baud, so
it obviously is not a good starting point. (More below.)
I don't need a terminal interface, since I will
be implementing a custom interface on the communications,
but I do need serial communications software that will
handle a 9600 baud modem running with compression.
1. Where could I find source code for such a beast?
2. Does the package support COM3/COM4 from the start,
or will I have to add the support?
3. Cost? Distribution rights?
4. Multi-tasking behavior?
5. Error-correcting protocols included?
I did try implementing the timer suggested in the source code
for tty.c in the SDK. The software was still routinely losing
characters, even with a timer message every 1/60 second and a
16K receive buffer.
Thanks.
