Thanks for your reply.

Oh, right - I guess that saves me a bit of coding then.  Have you read
the other emails?  I'll probably be needing to alter the way GDB sends
the characters to the parallel port when I code this protocol
converter.  Any idea what files I'll be looking at?

I've scanned a bit through serial.c and remote.c and found most things I
think.
