I have been using Zmodem to transfer network traffic for a couple years
now. Never have I had Zmodem hang or continue to send if the other system
locks. I call Washington,DC daily from California in an unsupervised event.
That's about as long distance as your gonna get without calling outside of
the country.

With Zmodem I get up to 1700 CPS. With UUCP-g I'm lucky to get 800 CPS on
a large file, average transfer rate is lower than that.
