   Combining GDB and user interaction on a target that only has one
   serial port is going to be a big problem.

It's not conceptually difficult.  Extend the gdb remote protocol to
support a command providing input on the serial port.  Add a command
to gdb to send a line of input to the stub.  Add a command to gdb to
switch the stub over to receiving input on the serial port until some
special character sequence is typed; implement this using the new
remote protocol command.  Implement the new remote protocol command in
whatever stubs you care about.

It's true that some things will be hard to do, like timing dependent
serial input.  Those are the breaks.
