An AT$EVENT command has to be set to send a GPS message to the remote host
when entering or exiting the fenced area.
Although this command accepts latitude/longitude parameters with up to 15
characters, internally the value is stored as a C float type which has less precision
(but requires half the storage size). The float type is capable of storing accuracy
commensurate with the GPS receiver's capability, but the queried
latitude/longitude values of the AT$GEOFNC command may differ from the input
parameters due to this precision limitation.
