 		 #177226 - Tx Rx pins
Responding to: ???'s previous message
May be your Tx Rx pins are connected wrongly. if your GPS to PC is working correctly and your 8052 to PC is working correctly using hyper terminal then you have to check that Tx pin on GPS is connected to Rx pin on 8052 directly without MAX232 chip.
