No.  The Versaterm manual does not show a hardware handshake cable.  To make
a hardware handshake cable, connect pin 1 (DIN) to pin 4 (DB25), and pin 2
(DIN) to pin 5 (DB25) instead of what they have.

(The cable they have allows you to detect carrier and to hang up, but you can't
do RTS/CTS handshaking).

Also, you will need to force the modem to ignore DTR from the computer-- in
every modem I've seen (not too many), that has been the first switch of an
8-pin dipswitch.
