remote protocol question

[Kumar Gala]

Andrew,

We are thinking of connecting GDB to a simulator over a socket.  The 
concern is that we stop GDB (via a breakpoint, control-C, etc.).  The 
simulator is able to take input from a separate console window.  It 
would be possible in that console window to then issue a set of 
commands to change the state of the simulation (NIA, GPRs, etc).  The 
question is if we can somehow ensure that when the user continues in 
GDB that the, GDB will have the correction notion of state.

Hopefully, that is clear, but maybe not ;)

thanks
