This pin out worked perfectly.

However, don't you have some of the pins labeled backwards?

For example, pin 2 is TX, 3 is RX, 4 is RTS, 5 is CTS, etc.

It seems like you gave the pins of straight through, but the labels of
null connection.

Not a big deal, it worked great, just wondered if you knew and had a
reason for that labeling.
