kgdb

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

Playing with kgdb on -current/amd64, on the remote, I see

  com1 at isa0 port 0x2f8-0x2ff irq 3: ns16550a, working fifo
  com1: kgdb

In /etc/remote (on the remote), I have

  com1:dv=/dev/dty01:br#115200:pa=none:dc:

to go with

  options KGDB_DEVNAME="\"com\"",KGDB_DEVADDR=0x2f8,KGDB_DEVRATE=115200

and

  # tip com1
  tip: /dev/dty01: Device busy
  tip: link down

As I wasn't in the debugger, kgdb shouldn't be using com1? (Why busy?)
Correct to use dty01 rather than tty01?

Cheers,

Patrick
