I have found that the only reliable numbers you can use for the Telebit
are the inbound figures. The Telebits tend to buffer the data on outbound
transfers giving very unrealistic figures when uucico does its calculations.

For example, I connect to a site on Saipan in the Pacific every night.
We both have Telebit T-2500s. Both of us show outbound traffic at over
800 cps but inbound traffic between 200-300 cps. (Don't be fooled by these 
low numbers. At least the modems can make and hold a connection. The 2400
baud modem I have can't connect at all.) The difference between outbound
and inbound seems to be simply the buffering effect of the Telebit on
the outbound files.
