Using Serial1 or Serial2, or multiple serial ports.

[Ghuru42]

I'm running on an ESP32 and I need a console to be on two serial port, both Serial and Serial1. Would this be possible? The trick here is that Serial is the normal serial that the boot loader etc uses, this port is used by a user to connect to the board and read/write settings. Serial1 is connected to a Nextion LCD that will write commands and poll for data. Having the same console interface on both serial port makes it all a lot easier.

Serial2 is used for modbus communication.
