SA4.TXT               STREET ATLAS 4.0 APRS INTERFACE

     This interface permits you to run APRS on an old DOS PC as a 
communications front end processor which then outputs GPS data it 
receives off the air via its second serial port to another PC which 
is running any other kind of GPS maping software.  Thus, any software
that expects GPS data can be used with APRS.  For details, see
COMMERCL.TXT.
