[aprssig] Spec question

[kb2scs at optonline.net]

Hi Matt
            All aprs software is supposed to accept upper or lower 
case. 
There was  perposall by Bob WB4APR that lower case would mean that an 
operator is at the controls of the aprs station. The software is 
supposed to change the Upper case N,S,E,W to lower case if the mouse 
has been moved. If the mouse has not been moved in X amount of 
minuets then the software is supposed to change the n,s,e,w to Upper 
case which is supposed to signify that no operator is present.

I do not know if any aprs software implemented this perposall. I 
would guess APRSdos has.
