Dragino Yun Shield with Arduino Mega - Serial1, 2 and 3


I have a Dragino Yun Shield connected with an Arduino Mega.

I would like to utilize Serial1, Serial2, and Serial3.

Whenever I try to begin a serial port [eg. - Serial2.begin(9600);], I get " no matching function for call to 'HardwareSerial::begin()' ".

If not, are there other options for receiving serial communications? I tried softwareserial, and AltSoftSerial with no luck.

Any help is greatly appreciated.

Thank you.

Edit - Apparently I forgot the baud rate in my begin statement. Carry on, as you were, nothing to see here, I'm going to bed!
