Did you look at the code? I wonder how well it would run over a
telebit to a unix host (in xmodem mode instead of uucp mode).

I had given some thought of doing something like this for a PC. The
machine in my living room has 2 337MB drives, but the one in the
kitchen does not have a drive for DOS. I am not familiar enough
with the ST to even think about doing what Paul has done. The C
portion may be able to be ported to a PC allowing the PC to serve
the ST.  I tried Paul's program connected to a 286 running Xenix
and all i get are "Chksum reading block 0" and then "Timeout"
errors. Has anyone been able to get this working on a ST talking
to a 286 or 386? I tried running it at 4800 baud with the exact
same results, the only thing i can think of is that the data that
the ST requires is byte swapped.

I have been giving some thought to using Paul's Unix partion of the
code to serve to a DOS machine allowing the same server software
to work with both the ST and PC. Anyone interested in swapping
ideas? Please respond via mail if you are, or know what the problem
is with running the C portion on a 286.

Is there a simple Backup program that works on a 520ST? The ST's
hard drive was dropped and i did not have a backup, hence my desire
to get pmfs working.
