I don't understand how to setup the serial ports.
There is a software and hardware which I understand the difference but in the initSerial i can only select channel 1,2 or 3.
What connects the channel selection to the proper I/O pin?

I found an example where you #define the SerRx pin and the SerTx pin but they have a high and low setting.
What is this High and Low for?
Also, what determines if the function will use the hardware serial port or just bit bang the signal?
