I used to experience similar problems with an identical configuration.
What I finally got to work was to use the command:

       sz -w 1024 filename
This seems to result in 512 byte packets being rather than 1024 byte
packets. Performance only decreased slightly; I now get about 220 cps
at 2400 baud, whereas zmodem should get 230 (with a clean phone line).
Still beats the hell out of kermit.
