Al,
I have not written any .ex programs for ages;
once I started with WinLib & Judith's IDE, coding
for Windows has been easy! So yes, I had no bother
with Windows (XP anyway). My only problem was the
tim eit takes Windows to pass back received data
to the caller; 30mSec or so, which makes serial comm
protocols a bit like hard work. I interface to external
UARTs through the PC UARTs which are presumably 16550's.
I have a general purpose Terminal program written using
the PCOMM.dll, and it is fine.
If you'd like anything sent to you, email me on:
andy at kestreltele.com
then I'll get it without having to remember to go to the
forum - which I forget to do when I'm busy!
Andy
