MEGA Hardware Serial

I've read posts about using pins 18 & 19 on Arduino Mega as the Rx/Tx. I understand these are Hardware Serial ports. On the board itself they are labeled RX1&TX1.

But there are also RX2&3 & TX2&3. So if I put my GSM/GPRS module onto RX2&TX2, would it also work?

Yes. Use commands Serials.available, Serial2.read, Serial2.print, Serial2.write

You meant:

"Yes. Use commands Serial2.available, Serial2.read, Serial2.print, Serial2.write", right?

He sure did.
