Monitor Serial1, Serial2 and Serial3

Hi guys,

I am working with arduino Mega and I am using Serial and Serial3 for a project. Is there a way to monitor both serials?

Thank you in advance

Is there a way to monitor both serials?

Yes, the Arduino is perfectly capable of doing that.

No, it is not possible to directly see the Serial3 data anywhere without reading it and printing it to Serial.
