Obviously it would be best if you can just move the disk, but if that's
not possible...
TCP/IP based methods are out of the question unless your Xenix system
happens to be one of the few that includes the SCO Xenix TCP/IP option.
As a last resort you could use Kermit to transfer the data through the
serial port with a null modem cable. Up-to-date Kermit versions are
available for both Xenix 2.3.4 and Linux:
http://www.columbia.edu/kermit/
I think the highest serial speed supported by Xenix is 38400bps = 3840cps.
You'd have to use Xon/Xoff flow control because Xenix doesn't support
RTS/CTS. At that speed it would take about:
(/ 600000000.0 3840.0 3600.0)
43.4
hours to move 600MB. That's a long time, but you can set Kermit up
to be super-persistent about getting the data across, so you can go away
for the weekend and reasonably expect to find the transfer done when you
return; see, for example, the "deliver" script in the Kermit script
library:

I'm including the Xenix newsgroup in this reply in case anybody there has
a better idea.
