Is it possible to implement two serial ports on Atmega 8/ 16/ 32 etc.
How to do that.
Is the concept of software modem of any use in such situation.
Any hint or link please.
 

You can use software uart for this purpose, multiplexer can also work in such situation.

If you use mikroC for AVR compiler then it has in built libraries for this purpose.

Few years back i used Software UART for PIC18f4550 micro-controller and that works for me in that project.
But i had used Software UART Transmission first and then Switch to Software Reception Mode.
