I need to change the transmission mode on a serial port to rs485 but when I go into the bios there’s no transmission mode select for that port it’s there for port 1 and 4 but I need to change it on port 2

    For consumer and off the shelf PCs I’ve never found RS485 to be supplied. That said the last time I needed RS485 I used some 14 buck USB RS485 dongle.
