The problem maybe the cable, as the SERNET files I sent you all work on my
systems.
Email the details of your cable to me and I will try and sort out the
problem.
Hello Derek,
I guess you got it to the point:
As far as I could determine using some primitive measurement (I am not a
hardware tinkerer) the cable I have does only connect 3 lines (see my ASCII
"artwork" below). So I guess it does not support hardware handshaking and I
guess the Sernet is configured for that...
Kind Regards,
Michael

the cable connects the lines (numbering as above):
  PC1 ---- QL1
  PC3 ---- QL2
  PC4 ---- QL3
This will probably not work.
You MUST connect handshaking (RTS/CTS) too, especially on non-Hermes 
equipped machines.
QL 'DTR" must be treated as CTS - well it _is_ that is fact.

I have not read thread yet, so someone else will have said this.
I won't give the pin connections, as I have not got my data to hand!
I always find this sort of pinout discussion amazing.
This was, I thought, put to bed in 1988/9 with the arrival of QuaLsoft 
File Transfer, where we laid out quite clearly the necessary pinouts.

Dilwyn has written a treatise at the end of a similar discussion on this 
mailing list a few years back.

It seems some subjects will never die (8-)#
