I think you got closest. There is apparently something problematic about the way modem control is wired through my cables. While I was arsing around, grasping at other sorts of proverbial straws, I ended up with the same cable plugged in with the ends the opposite way around and it started working fine. Swap ends again, the fault returns. I figured since the VAX end doesn't use modem or flow control, it wouldn't matter how they were or weren't wired. Wrong! ok bear. -- until further notice
