To be perfectly honest, I'm not familiar with zmodem. However,
there was quite a bit of discussion in one of our ISP-local news
groups about disconnects at 10 minutes during transfers using sz.
It was reasoned that 10 minutes indicated the idle daemon kicking
in and logging out sessions, and the solution was found to be to
use an sz option to enable windows. Why does sz offer this
feature, if it's known to be detrimental in some way?

Um, perhaps Frank may comment on the validity of the rest of your
test, but
>time kermit -s b17mh.gif
tells Kermit to do newline and charset translations, which might
account for some CPU power. At the least, you'd have a corrupted
gif file on the other end.
I think the command you wanted was 'kermit -s b17mh.gif -i'.
Also, did you have control character unprefixing set up for
C-Kermit? Excessive prefixing may also account for some CPU time.

Does this software not tell the user whether the file transfer is
taking place in BINARY or TEXT mode? (If it does Kermit transfers,
does it not process file attributes packets?) MS-Kermit puts the
transfer mode right up there on the screen, so if the transfer is
accidently started in the wrong mode, the user may observe that and
restart.
