It wasn't until I began adding "-l 1024" to my SZ calls that I was able to
get successful downloads to my PC.  The path here is really offbeat:

			host-Develcon-T1-Develcon-modem

My guess was that flow-control wasn't happening in real-time with all the
intermediaries, so that using "-l" would force explicit handshaking.

It takes a bit of a performance hit, but I still get over 200 cps on a
2400 baud modem.  Has KERMIT thruput (with its 90+packet size) beat by miles!
