Re: Protocol Translation (Apologies for LONG email)


Hi Bill,

Thanks for your reply...

Hmmm, good idea, I'd not thought of that.  I've not really looked at the

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.
