@cindex remote stub, support routines
The debugging stubs that come with @value{GDBN} are set up for a particular
chip architecture, but they have no information about the rest of your
debugging target machine. To allow the stub to work, you must supply
these special low-level subroutines:

First of all you need to tell the stub how to communicate with the
serial port.

Write this subroutine to write a single character to the serial port.
It may be identical to @code{putchar} for your target system; a

@end table
If you want @value{GDBN} to be able to stop your program while it is
running, you need to use an interrupt-driven serial driver, and arrange
for it to execute a breakpoint instruction when it receives a control C
character. That is the character which @value{GDBN} uses to tell the
remote system to stop.
Other routines you need to supply are:
