but I've not setup a 485 adapter and written any scripts to check it yet

The KS-24361 discussions pointed out that you can just wire things across if
you pick the right polarity on the 485 side.  It works for me.  I wouldn't
want to count on it for use with long cables, but it's quick worth a try for
a one-off setup.

As I remember
For rs422 receive plus to ground and rs232 to minus.
For rs422 xmit take the minus to the rs232 line.
This has to be a modern rs232 port that will work on 0-3V or greater.
As Hal says it works over 3-10 ft. May go further but it is a hack. the
price is right.
