This appears to be the case that runs into trouble on my system when I
use xon/xoff.  I don't use hardware handshaking because my ports
apparently don't know how, and (since dropping xon/xoff) I've had
faultless UUCP with two other Trailblazer sites, one of which provides
news at up to 20 MB/day.

So my experience is directly opposite yours, especially when I recall
that I used to use xon/xoff at 2400 bps without a hitch.  Could you
explain where I'm confused about what you're saying?

Thanks,
Pete
