Hello,
See also this earlier PR:
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=17919
I think, depending upon the port, changing the cnmagic value on its own
might not fix this problem, e.g. on hp700 it's set to "+++++", but
sending a break on the console also drops to ddb. (I see that cobalt
doesn't have an entry in ddb(4) under "Entering the debugger".) The
earlier PR notes that using ddb.fromconsole=0 effected the desired
behaviour.
Regards,
Dave
