Noel,
That makes a lot more sense. I'm still trying to locate source.
Thanks,

If this means it got signal 16... or 1 from the
sysinit call (called
from main)
I'm not sure that interpretation is correct. I think that trace shows signal()
being called from sysinit().
On V6, signal() was a system call which one could use to set the handlers for
signals (or set them to be ignored, or back to the default action). In. 2.11
it seems to be a shim layer which provides the same interface, but uses
the Berserkly signal system interface underneath:

https://www.tuhs.org/cgi-bin/utree.pl?file=2.11BSD/man/cat3/signal.0
So maybe the old binary for kermit is still trying to use the (perhaps
now-removed) signal system call?
