[time-nuts] OT: Prologix GPIB and HP3478A...

I'm sending the commands as I type them in Kermit. Surely that is slow
I cannot send any commands to the 3478A. The simple act of asking the
prologix to do anything other than ++ver, locks up the prologix so it
ignores all USB traffic.
The Prologix works fine with a 3438A, which is about as old as GPIB
gets. Also with a 3437A, which is pretty old too.
Something is broken here. The prologix is probably violating some timing
requirement in the handshaking, and the 3478A isn't playing along.
