Hi,

I would like to know more of GDB internals especially the control flow and
functionality for the following gdb commands. For ex. the development
environment include gdb on cygwin environment, which is connected to
OpenOCD, which inturn connects to ARM target. Any information on this
would be very helpful.

1. target remote host:port
2. stepi
3. contrinue
4. break linenum
5. delete bpnum
6. watch expression
7. set/read register value
8. read/write memory
9. quit
10. monitor reset

Thanks in Advance
