Class GPSrxtx

java.lang.Object
  gps.connection.GPSrxtx

public final class GPSrxtx
extends java.lang.Object

This class implements the low level driver of the GPS device.
The serial link reader is defined as a State. The State defines the protocol.
The getResponse() function should be called regularly to retrieve and interpret the GPS device's response.
