Hi
I'm communicating to a HP33120a function generator. PC and instrument are
both DTE devices and I use a null-modem cable as described by HP.
When I run the software I have written in LabWindows I sometimes get errors
from the instrument. Header errors and "Input Buffer Overflow" errors
Also for purposes of setting up a larger test system which includes scopes
and multimeters too I have purchased some USB-Serial Adaptor devices. But
when I use those with the same serial flow as with the null-modem cable I
get more errors.
So I need to do some debugging, but it seems too difficult with the scope. I
have an old portable PC, can I somehow hook that up as a second idle PC to
the same serial line with some sort of port state logging software to get an
idea of where my problems comes from?
Thanks
Klaus
