Hardware definition:
GPIO on HYSTOU mini pc P12-i5-8250U:
On P12-i5-8250U, COM1 and COM2 can be changed to RS232, RS422 and RS485 from Bios, guide pls click here, other 4 COM port definition below:
TXD3+RXD3+GND = COM3 (RS232)
TXD4+RXD4+GND = COM4 (RS232)
TXD5+RXD5+GND = COM5 (RS232)
TXD6+RXD6+GND = COM6 (RS232)
Totally it is 6 COM port onboard of P12-i5-8250 mini pc.
