Yes, Initially I set LOWER case as the way to indicate a LIVE
person since all the existing unattended things were all
UPPERCASE.  But of all the programs out there, Uiview (which
cannot be changed) would completely ignore the lower case posit.
Hence, All "attended" stations would disappear from Uiview.  So,
it was not the way to go.

We reversed it so that Uppercase means attended for those that
send the bit.  It will take YEARS for software to catch up...
