[Elecraft] OT: RS232 ports on newest desktop computer motherboards

Nothing new here, I'm sure; I simply was happily reminded of this during
research on gaming machine motherboard candidates.

The mobo mfrs seem to disguise the naked (9-pin!) RS232 headers on their
boards with names like "COM", "LEGACY", etc.

Have a look at your own board's naked headers, if you're wanting to avoid
converter-cable problems involving USBx, where x varies from zero to
infinity.  The header-to-9pin-dogbone-connector ribbon-cable things are
available to reach from the header to the card-slot on the case backdrop. 
Then you can use LP-Bridge to share the port.

If you're interested in the research results, email me off-reflector via the
ARRL email reflector, thanks.

Brgds,
Dave, N3HE
