hello sir i used atmega 32 with gsm modem and get performance best.
now i am planning to connect gps and gsm modem both with atmega32.
but this mcu have only one tx-rx then ,how these two modem can be connected with one serial port of atmega32,then where i will connect my gps modem to receive signal.

plz help me
 

Use a relay for that purpose. connect normally open to GPS and normally closed to GSM. So at power on by default GPS will be connected. if you operate relay whenever required GSMwill be connected
 

good idea. so the quad switch is a low voltage operating relay.
