How to create a serial port using timer?

I do this with the help of micro controller ATmega32

Somebody who can help me?
 

If you want another Timer other than the hardware one, that usually comes built-in in microcontrollers then you can use software timers- a technique also called bit-banging. In this technique you can just shift your data( stored in any variable) left or right so that it can be escaped out from a desired pin-out of the microcontroller in LSB first or MSB first orders.
This a pretty neat technique especially when done in an interrupt driven manner and will have lesser glitches.
