I've watched some connections with -x9 and find that after the R
command is sent the remote site fails for some reason and the
local machine times out. This happens so many times I would like to
get some opinions as to why this is happening. The two sites I have
seen this occur repeatedly is avatar and osu-cis. Any insight would
be helpful.
Thanks.

Of course it's hard to say without more details, but I've had a similar frustration here. SUNY Oswego installed a new, state-of-the-art digital (Intecom IBX) phone system. The ports on the computer center's vaxen are connected at 9600 baud over digital (ITE) lines, and calls to/from the outside world are routed through a pool of 2400 baud modems. Evidently buffering in this system "gobbles up" uucico's ACK's and leads to similar symptoms. The small number of characters sent by the remote site's uucico is not enough to flush this buffer, and the two systems get "out of sync" with each other, leading to a series of "alarms" and eventual failure. We tried lots of things to get UUCP working between cboard and oswego through this modem pool, but finally gave up. They now have reverted to a modem in the machine room on an analog (STE) phone for UUCP use. Now UUCP works reliably.... ||| Boyd Ostroff - Tech Director - Dept of Theatre - SUNY Oswego ||| Sys Admin - "The CallBoard" - (315) 947-6414 - 1200/2400 baud ||| ostroff@oswego.oswego.edu - cboard!ostroff@oswego.oswego.edu
