Executive summary:  It works!

More detailed exposition:

I logged into athena.dialup.mit.edu, and got BOLOGNESE.MIT.EDU.  Using
/mit/modem/decmipsbin/kermit.new, with the following settings:

	set window 5
	set receive packet 1024
	set send packet 1024
	set block-check 3
	set parity none
	set flow none (on the dialup)
	set flow rtscts (on my Linux box)
	set terminal bytesize 8
	set command bytesize 8

I then tried sending and receiving an 135,257 byte file.  (/etc/termcap
on the Decstation), and it worked.  Using the above settings, I got the
following statistics.  Effective data rates of 1433 cps and 1389 cps are
quite good, considering that the modem connection was 14.2 kbps.
