I want to connect my OPNSense box to my APC UPS via a serial cable. The problem is I can't find the serial port information.
I run
/dev/ttyu0
/dev/ttyu0.init
/dev/ttyu0.lock
How do I find my serial port? How do I get OPNSense to leave it alone, and not try to output console information via the port?
I run
Code Select
ls -l /dev/tty*
and it only shows 3 items:/dev/ttyu0
/dev/ttyu0.init
/dev/ttyu0.lock
