What a load-O-$^&%

I spent a number of years working on combining many instruments from many
makers into automated test systems and was the defacto company interface
guru.

When something says it is an RS-232 serial port, that is just a hint to
starting the connection issues.  The IBM PC serial cards really helped
straighten out the mess because many companies decided that it was the most
common and well documented version.  There is still a lot of equipment that
swap the lines or only use odd combinations or none of the handshaking
lines.  Many also use improper voltages even though the chips to add the
proper voltages are cheap.
