GDB contains documentation. See
http://sources.redhat.com/gdb/onlinedocs/gdb_14.html#SEC116 although be
aware that you can ignore the section "what you must do for the stub"
beacuse eCos does that for you.

Something like +$T05:00012345;1a:123532242;# should appear when you connect
to the target directly using a terminal program like minicom or cu (or
hyperterminal on Windoze).

Yes, assuming 19200 is the correct speed for your particular board. Most
are 38400.
