- Dear reader:
- This code is based on the premise that if GDB receives a packet
- from the stub that begins with the character CAPITAL-OH, GDB will
- echo the rest of the packet to GDB's console / stdout. This gives
- the stub a way to send a message directly to the user. In practice,
- (as currently implemented), GDB will only accept such a packet when
- it believes the target to be running (ie. when you say STEP or
- CONTINUE); at other times it does not expect it. This will probably
- change as a side effect of the "asynchronous" behavior.
