Subject: Machine-to-machine file transfers

Use any version of Ward Christensen's MODEM program (MODEM7xx, MDM7xx,
MODEM2xx) and connect the two machines together using RS-232 serial
port.  Set the ports for 8 data bits, one stop bit and no parity.
Reverse the connections on pins 2 and 3 on ONE END of the cable
connecting the two machines.  Make sure the baud rate is identical on
both.  Test path using the "T"(terminal) mode on each MODEM program
before trying transfers.  You should be able to type on one machine
and see it on the other.  Set baud rate for highest that will support
error-free transfers (I use 4800 baud).  Initially start at 1200 (or
even 300) baud to debug the connections.  If you use MDM7xx, you'll be
able to use the "B"(batch) mode which allows multiple transfers with
commands specifying ambiguous names (like SB B:*.*).
