Hi Didier, I have exercised this problem both with kermit (a terminal emulator), and with a Python script under linux. It occurs both fast and slow. At no time does the 3478A give any appearance that it thinks it is on the bus.
I am pretty sure that the Prologix is, uhmmm, speaking out of turn. It thinks the 3478A should be at a different point in the handshake sequence than the 3478A thinks it should be in. The main clue is in that the Prologix restores itself when I disconnect it from the 3478A. -Chuck Harris Didier Juges wrote: > Chuck, > > The commands I copied in my previous post were sent very fast.
