First Claim
Patent Images
1. A method for automatically detecting a GPS receiver and configuring a communications port on a computer that is connected to the GPS receiver via a communication link, comprising:
- initially setting the communications port to default settings;
determining whether a protocol associated with the GPS receiver is detected;
if the protocol is not detected, sequentially resetting the communication port with different settings and redetermining whether a protocol associated with the GPS receiver is detected; and
wherein determining whether the protocol associated with the GPS receiver is detected comprises;
waiting for a termination character to be received;
once a termination character is received, receiving a message;
searching the message for a sign-on string;
if the sign-on string is not found, searching the message for a termination character followed by a start character; and
if the termination character followed by the start character is found, indicating that the protocol was detected.

Abstract
Methods for automatically detecting GPS hardware are provided. The methods attempt to determine the protocol of a GPS receiver by adjusting variables related to the protocol of the GPS receiver. The variables may include baud rate, protocol, or any other desired variable. Following determination of the proper configuration settings, the methods determine the communications port to configure with the appropriate settings.
