GPS Intermediate Driver
When the first user of GPD1 opens the port, the GPS Intermediate Driver opens the COM7 port. The
GPS Intermediate Driver allows multiple applications to open GPD1, and the GPS data is broadcast to
all open ports.
When the GPSID driver is in use, the COM7 port is allocated to GPSID as READ|WRITE (COM7 is still
available for access mode of 0).
