Before I start whacking away at cables, I'd like to know what experience
anyone has had with making hardware flow control work between a
Trailblazer and a MicroVAX II running Ultrix 2.0. We're having the
typical problem where you don't want ^S/^Q on a line being used by
uucp, but do want interactive dialup to/from slower modems to work.
Any hints appreciated,

The ACKs in the 'g' protocol provide enough flow control. Besides, I assume that when the Trailblazer goes into 'g' spoofing mode it disables xon-xoff processing. Jerry Aguirre

UUCP takes care of itself OK, but when a user cats a file, you need some flow control to keep the CPU from overruning the modem. -dB "Do you programmers do sh*t like this a lot?"
