TX3 on Mega board?

Hi, I am asking myself why there are TX1-> TX3 and RX1-RX3 on the MEGA board. I thought I can generate software serial ports as many I want to.

If TX3/ RX3 is a dedicated RX/TX how can I access it?

Can someone explain to me? :-/

Software serial ports and hardware serial ports are two different things. The mega 1280 chip has four internal hardware serial ports. The mega 168/328 has one internal hardware serial port. If TX3/ RX3 is a dedicated RX/TX how can I access it?

All explained in the Arduino reference documentation: http://arduino.cc/en/Reference/Serial
