M5Dial can port a or b be used as a second serial port?

Just started playing with the M5Dial and have it working using the USB as a serial port in Arduino. Is there a way to configure either Port A or B as a second serial port in Arduino?

@Shanks-0 software serial?

@Shanks-0
Port B is generally a no as one of the pins is normally input only

@robski I don’t think SoftwareSerial library is available for the M5Dial but I will have a look.

@Shanks-0 its like with M5Core basic with just one port which pins then can be defined to be uart/I2C/GPIO

@robski I managed to get it to work on Port B, defined the pins in Arduino and used:
Serial1.begin(9600, SERIAL_8N1, rX1, tX1);

Works well.
