There is a kermit list called IKD (Info Kermit Digest) available
on some litservs. I don't remember where I subscribed. The Digest
is edited at Columbia U. It didn't come all to often in the last
couple of months, but when it comes it is full of information
for just about all kermit implementations from c64 to xa, cms
and all the rest.
 
Hope it helped
