[Xastir] WX station interfacing

[Rick Green]

Last spring at Dayton, I splurged and bought myself a refurbished Peet 
Bros. weather instrument, an 'Ultimeter 500'.  It has a 6-pin rj-style 
connector on the side of the display unit, which according to the manual 
can be used for the optional PC data logger.
  I seem to remember a mention here that xastir supports the peet bros 
stations, but now that Fall is rapidly approaching and  the weather 
station is floating to the top of my round tuit list, I am finding a 
dearth of information on how to accomplish the interface.  The wiki 
advertises support for many different weather stations, including the Peet 
bros U2000, but the manual and Wiki don't even have sections started on WX 
station interfacing, and the 'Aadvanced usage' section simply says 'TBD'.
  I read thru 'wx.c' in the source tree, and found some rough examples of 
the data strings that the U2000 puts out.  Now if someone could just clue 
me in to a proper RJ- to DB-9 cable pinout, I could start the process of 
learning the differences (if any) between the U500 and U2000 datastreams, 
and hopefully get another WX station on the air.
