This is a problem regarding locking.  HDB UUCP keeps locks in /usr/spool/locks
and futhermore stores the ASCII PID of the locking process in the lock file.
Kermit DOES have support for HDB, however it's not defined correctly in the
sys5r3 rule in the kermit Makefile.  Simply add -DATT3BX to the rule for build-
ing the sys5r3 version of kermit and everything should be fine.  Examine the
C program "ckutio.c", it's obvious in the code what the ATT3BX is supposed to
be used for.  It would have been more appropriate to call the define HDB !
