ZModem alwaysuses delayed ACKs... the only time that Kermit is faster than
ZModem is when it can compress the file using run length compression... so ZIP
files do not transfer any faster for example.

Kermitas of last time I looked at it used a fixed packet size, ZModem uses and
adaptive packet size... ZModem is also about 100 times easier to set up and
use.
