By the way:
I have sent the Delphi test program I am debugging over to people at
the remote location and they have connected their laptop directly to
the data system and with that setup there is no data loss.
So this leaves me with only the Lazarus/FPC network relaying app to

I could also create another test program, a serial sniffer that could
be set up to just log whatever appears on the serial lines. I need a
3-way cable for that of course.
