Yes they do, I've been using one for years. The Delorme's are decent
little units with WAAS capability. At one time you could buy them
with a serial port adapter cable but I believe the new ones are USB
only.

A lot of the DeLorme units aren't designed to work with anything but
their own software and aren't true standalone GPS units. Another
reason to avoid them is that none AFAIK of their units are IPX7 water
resistant.

The low-end Garmin is probably a better bet.

Also on the issue of NMEA black boxes...they're generally called NMEA
multiplexers.. A good unit can be seen at:

They make ones with RS-232, USB or Bluetooth capabilities. Also, some
of their units will translate from Raymarine Seatalk to NMEA.

Not really needed if you only have a few (usually up to 4—VHF, HF,
AutoPilot, PC) NMEA devices which need the NMEA output from your
GPS...the Bluetooth does make connecting your computer much simpler.
