If you look at the source file, ckutio.c:
ftp://kermit.columbia.edu/kermit/f/ckutio.c
you'll find a routine sndbrk(). You'll see that it has a multitude of
#ifdef'd code selections because Break-sending is perhaps the least
standardized of all Unix APIs.
See if you can find Mac OS X documentation on how to send Break. Hopefully
the recommended method matches one of those already selectable in sndbrk().
If so, "just" finagle the #ifdefs to select the appropriate code. The
symbol for Mac OS X is MACOSX.
Let me know what works and I'll add it to the C-Kermit code base. If you
have questions, send email to kermit-support@columbia.edu.

This kind of comment should be sent to us too. What kind of trouble?
What changed in Mac OS 10.2.6 that might have caused it?
