Use this message to create/edit polygon-defined regions. Managing
a region is different than managing any other configuration parame-
ter, this because a region can’t be defined only with one
GR
message,
instead, several messages are used to create a region, one for every
point the region has. So when you use a
GR
message, you are creating
or editing only a region’s point.
The Active Flag of the message is used to set the last point of a
region. To undefine a region simply set the Active Flag of the first or
second point
13
to
U
. The message has the following format:
