It certainly seems that kermit is the more robust protocol. Zmodem may
be faster on clean 8 bit connections. Both protocols suffer, however,
from buggy implementations, which may make it seem that the protocol
is ineffective. For zmodem over telnet, you may want to use the "-e"
option, which escapes all control characters. Most DOS implementations
that I have seen other than those by Chuck Forsberg of Omen Technology
seem broken. I would make sure that I was using dsz/gsz/zcomm/pro-YAM
on the DOS side before deciding that zmodem itself doesn't work over
telnet. Modern versions of kermit seem as fast as zmodem over clean
connections when properly configured, but can almost always be made
to transmit the data accurately even over very poor connections.
DOS/Windows implementations of kermit seem even worse. Kermit versions
from the kermit project should be used if you want to evaluate kermit.
