I'll have to second this (all of my _one_ modems).  The machines I'm dialing
in to are using 9600 DTE rates (or are floating the baudrate--not sure how
you *nix-er's do things), and I get ~770cps with batched news and around
that for zmodem transfers.  I'd expect to get higher throughputs with their
ports opened to 19.2.  Would it be a good guess that uucico enjoys an 80%
effective throughput (20% overhead with 3 windows?)?  Couple that with phone
line degradation and ~1100cps may be max.

Remember the days when we tried uucico with USR HST's at 38.4?  ~340cps with
a tailwind (my phone bill STILL hasn't recovered. :-)
