Hi Bill,

Thanks for your reply...

Hmmm, good idea, I'd not thought of that. I've not really looked at the
gdbserver code, so I think I'll have a dig around in the morning. It

I'm not sure I understand you here, "parse a configuration file"?

Do all GDB messages go via the gdbserver?

That's a plus. I'm still flip-flopping between actually adding-IN to
the GDB code or (like this) adding-ON to it.

Thanks again for your help.
