If the new Samson HP50G serial cable is true RS-232 would I need a
null modem cable for two HP50's to talk to each other? If this is
true do they make anything like a gender changer in format that does
the same thing as a null modem cable?

Wouldn't the IR port work better for that purpose?

Not really. The IR has a range of only a few cm.
I would eventually like to connect my HP50G to a Vernier LabPro
interface. Also I am going to try connecting it to my Triplett
Multimeter that has a RS-232 interface.
It seem that this method would be better suited for transferring data
collected in the field to another calculator for analysis.

If you mean two identical, non-configurable calc+cable packages
head-to-head, thru only a gender changer, that would connect
RX to RX and TX to TX, so that neither would listen to the other,
so a "crossover" ("null modem") would be needed between them.

So it is said, although you can always find one of each adapter type
(gender changer + null modem/crossover), which can plug into each other,
or even make your own from two male plugs and 3-4 wires.
