Interfacing GPS with 8051

[K2DGR8]

I am currently working on the project related to vehicle security & tracking using GPS & GSM.
How can I interface both GPS & GSM Modules with the only Serial Port of 8051?
GPS Module is to be connected to RX pin of 8051, while I need both TX & RX pins to connect to GSM(Communication with GSM Module is Bidirectional).
