Paul,

The only thing I can still try is to, instead of a z-modem cable, use one
with the signalling lines connected too. That will have to wait until I
can find the cable for it though.

I realized I had still had my crossover dongle, and even could find it back
(Jay!). Alas, no change.

I can't get copy.exe to exit,

Same here, regardless of the used cable (z-modem or full-wired). Only
"type com1 datafile" works /somewhat/ on the DOS 'puter - I still have to
press Ctrl-C, which "^C" output than (ofcourse) also gets stored in the
file. Not that that is the only thing, as the output file also starts with
a slew of NUL (0x00) chars.

It looks like that copying a textfile over COM1 is a bitof a tricky
business...
