Summary: Kermit uses ^A

Thanks for mentioning this.  I always wondered.

The entire kermit protocol is based around ^A.  While it depends
on the transaction being sought, a kermit packet will always
begin ^A-printing character- (1-94 characters) followed by a return.

Normally, kermit must be in "protocol mode" to trap the ^A --
ie, it only looks for packets when you ask it to.  But it wouldn't
be too hard to change this.

Actually, if you store files in binhex form, what you propose can
be accomplished already with the PD. kermit.  Just establish a
user "kermserv"
	kermserv:xxxx:9999:9999:/usr/spool/uucppublic/:/usr/local/kermserv

/usr/local/kermserv:
	kermit -x

And anonymous users can upload and download to their heart's content.
Kermit is a far more reliable protocol than the alternatives, and
it allows for wild-card downloads.  So even if it is a little slower,
I just start up 10 files and walk away for dinner.
