   I'll pull together some data dumps of the U500 datastream, but probably 
not until tomorrow evening...
   When I first implemented it, I discovered an off-by-two error in the 
parsing of, I think, the wind direction(?)  I corrected the source 
locally, recompiled and tested it here, and posted the diff to the list, 
but I never saw a response that a developer had picked it up and committed 
the change.  Do you remember seeing that, or should I also search my 
sent-mail to resurrect that one?

  Darn.  How difficult would it be to implement?  I was looking at the 
ser2net package running under openwrt on an Asus WL-500gP 'appliance' to 
better locate my wind and temp sensors.  I've found some commercial 
solutions (B&B Electronics) which include a driver to implement a 'virtual 
serial port' locally, but that's more $$$ and closed, so I don't want to 
go there.
