I made up a serial cable.  I've had problems in the past, because the
signal level ranges are different between RS423 and RS232 and even
though theoretically there shouldn't be any problems, some hardware won't
talk.  My PC seems to talk to the beeb fine, though.

I've been transferring files by running this program at the Beeb end :

       10 *FX 3,3
       20 *DUMP <filename>
       30 *FX 3,0

and just doing :

       cat < /dev/ttyS1 > <filename>

on the PC (hey, it's easy when you're running UNIX :-)  I then wrote a
short C program to convert the *DUMP format to a binary.
