My thinking is that some tcl commands return tcl output. Tcl commands
in via monitor commands and tcl input back.
The GDB "mon" is just the channel/transport.
The response from such commands must encode success/failure,
exception text and result if any.
Perhaps a prefix command a la
monitor openocd_tcl {xxxx}
=>
here the result encodes:
- exceptions(if any)
- resultant text
- resultant human readable text
all in easily parsable form(for Tcl anyway :-).
The above "opencd_tcl" command would work with any of
the supporte transports(Tcl connection, gdb mon or telnet).
