Having just fetched and compiled and new kermit, I tested 8-bit transfers
and found to my delight that they now work.  Previously, I could not get
them to, and had to resort to slower 7-bit transfers for binary files.

With a measured raw "cat" rate of 225 characters per second (2400 bps
modem), I get 180 to 190 bytes per second of compressed binary transfer
with kermit and the following .kermrc file:

set file names literal
set file collision overwrite
set file type binary
set terminal bytesize 8
set parity none
set block-check 3
set receive packet-length 900
set send packet-length 900
set window-size 3

The crucial commands here to get the performance are "set parity none"
(which is the clue to use 8-bit transfers), set window-size 3, and
the set packet-lengths.

I have uploaded the compiled kermit to kermit5a.182.tar.Z to the
pub/next/submissions directory on sonata.cc.purdue.edu.
