Al,
I think that I got the PCOMM.DLL off the Euphoria
contributions page! About 2001 - that's the file date.
I assume it is still around, but if not - well, I have
it and the PCOMM.ew and my (pretty rough) Terminal.ew
all zipped up ready for anyone who wants it.
As for source no, I have none. I don't know for sure
that PCOMM.DLL was not a purchased item put on the
contribs by its purchaser. I have no information about
it beyond ...... aahhh!!! I have someplace a documentation
file - I have a printout of it here in my hand! Let me go
hunt for it ... Aha! Yes, it was all in a zip file which
I seem to have as ser_comm.zip, and therefore I am sure
you'll find it in the archive. Yes, I have found it:
WIN Serial Communications 82K Kondor Attila May 2/05
Go get it and see what you think. I guarantee it works on XP!
Andy
