   And this is about as it should.  As far as I understand Kermit
protocol only uses the 7-bit half of each bit in the transfers, and
thus looses out in speed.  On the balance, over difficult transfer
circumstances kermit often is the only protocol that gets through. 
This is a classical case of different tools for different
circumstances. 
   If you are interested in more information, there were some
interesting messages about kermit transfers in the news recently. 
You can get them by downloading /pc/ts/tskerm22.arc by anonymous ftp
from our site.  The messages are duplicated with the kind
permissions of the authors.  Tskerm22.arc also contains a number of
MsKermit utilities. 
   I also agree with you about the usefulness of z-modem.  The big
problem I have had with it is that I have managed to get only
DSZ1019.ARC version, and Telix z-modem (which I use) work properly. 
With all other versions I have had one problem or another (and
although my technical knowledge is limited, I can claim some
experience with file transfer problems).
