First - while Kermit is worth having a copy of, it is not worth "buying" -
you can download a free copy from Q-link, or get it from other P.D.
sources (If I'm pressed I can even upload and E-mail you a copy Mr.
Mullen). As for data transfer speed: I use Kermit to X-fer stuff from
our Unix machine at work to my CP/M (gasp) machine at home: Kermit
takes (about) 10% extra bandwidth to transmit a file (assuming text -
if it's a binary it gets worse). So 4096 characters of data will need
about 4500 characters transmitted over the line. Now 300 Baud is 30
CPS, hence 4500 chars take 150 seconds - 2.5 minutes, and at 1200 it's
under a minute (about 40 sec). A fair estimate that will put you in the
correct ballpark for data transmission is that a K takes about 10
seconds @ 1200 baud.
