Remote and CNTRL-C + X packet?

[Andrew Cagney]

Hello,

(Here's one for the remote-protocol police).
When GDB wants a remote target to stop it can either perform an
out-of-band ``break'' or send the CNTRL-C character.

Technically this makes a singe CNTRL-C a packet in its own right (arrg
:-). Should the protocol specify that a CNTRL-C is only valid outside of
other packets (such as X).  Should it be sent within a proper packet (I
suspect some existing targets would ignore it).

	slightly confused,
