Much of this file (in particular the SWI stuff) is based on code by
David Taylor (djt1000@uk.ac.cam.hermes).
I hacked on and simplified it by removing a lot of sexy features he
had added, and some of the (unix specific) workarounds he'd done
for other GDB problems - which if they still exist should be fixed
in GDB, not in a remote-foo thing . I also made it conform more to
the doc I have; which may be wrong.

I'be been unable to make it reliably sync up with the change
baudrate open command. It likes to sit and say it's been reset,
with no more action. So I took all that code out. I'd rather sync
reliably at 9600 than wait forever for a possible 19200 connection.
