  Running Kermit (with packet size 512, 3 windows) between an old HST (9600
baud top speed) and a Rackmount Dual Standard, I get 1060 CPS on binary
files. If I replaced my old HST with one that spoke either V.42 or the new-
er HST protocol (14400), I'd see a proportional increase.

  Of course, this doesn't address the UUCP g protocol, but since it's also
a windowing protocol you should see similar results. I have seen reports of
UUCP transfers over V.32 modems where the transfer rate is approximately
equal to the CPS rate through the modem.
