Okay - are you east or west - Sydlley I think is 5 hrs ahead of
Singgers, Perve is about the same as me?

Sounds like all the obvious stuff is okay - are you saying that the
(HP?) it is not sending and not that the (PC?) it is not sending?  And
that therefore your PC stuff may all be okay?

>You speak SCPI?

Unfortunately I don't know what on earth SCPI is - I can just get the
PC side sorted out for you once you get the HP to send data.

I apologize if I shouldn't have answered this, not knowing SCPI, but
if it is any kind of a PC/QB serial problem, I have probably done more
work with that than anyonbe else on the planet when it comes to
connecting to all kinds of other serial devices like data loggers,
sensors etc.

Is it possible that HP is waiting for a control line to go on from the
PC side, or for the PC to send an initial XON or something dopey like
that, before transmitting any data?

To verify that QB is not doing something stupid for you, can you
(easily?) try hooking the HP up to a terminal program like the old
CROSSTALK or similar, or possibly Windows hyperterminal without
getting too bogged down in that as a separate exercise?  This used to
be an easy way for me to sort stuff out on occasion.
