We've been playing with uuslave. It is a crafty little bit of code.
It condenses a lot of the usual uucp code to give a prog. that
will run on almost anything and allow uucp file copies and *mail*
transfers. So far its run on BBC's and ATARI ST's

The only system dependant bits are:
(1) opening the serial port, setting it to RAW mode no ECHO and
    8 bits (thats where the inita stuff comes in)
    In most micros you can just open it. (fdtty=open("rs423:",3) or sim.)
(2) the read and write code (xgetc() and xputc())
    xgetx() is tricky in that it should timeout after 10 seconds
    if it doesn't get a char. You can use polling if you don't have signal()
    But in fact it will work most of the time without a timeout.
