is this possible to use same serial port of 89s52 for different purposes?

AMIT KULKARNI

In my project i want to interface a GSM modem and 24c02C i.e EEPROM (I2C based)to microcontroller.
so now i am not understanding whether can i use same Rx-Tx pins to interface microcontroller (89s52) to EEPROM and GSM modem as well?? if not then is there any other microcontroller of AT89cxx/AT89sxx family with 2 serial ports?
and which will support embedded c and assembly too!

    no u getting me in the wrong way..:o
    that is between you and micro (u)

    in previous comments i had got a reply that "u should choose the microcontroller better than the one u have chosen.."
    NO, YOU DID NOT, the responders here so not use Stupid Monkey Shit, you got
    You should choose the microcontroller better than the one you have chosen.

    thats why i am asking...
    I can't tell what is the problem with 89c51re2?? without reading the dayasheet, do that yourself. The requirements were revealed to you above.
