Allen Briggs added a "kgdb" command to ddb a couple of years back.
Here's part of the commit message:
Add a rudimentary 'trap to kgdb' command if KGDB is defined. This allows
systems with only one serial port for console, etc., to have at least some
basic access to remote-kgdb-over-serial, even if it is a bit awkward.
I haven't used this myself, but it should be possbile...
Simon.
