Disable serial console?

  • Hi! I'm trying to use a serial GPS with my pfsense box which only has a single serial port. Unfortunately pfSense keeps stealing the port for the serial console. I've tried commenting out the offending lines in /etc/ttys and /etc/gettytab but is there a (official) way to disable this that will survive reboots?

    Does the system have a VGA console? If so, the serial console can be disabled from System > Advanced, on the Admin Access tab.

    If the system only has a serial console and only one serial port, then you can't disable the serial console since you must have at least one console.

  • It doesn't have VGA, but it does have HDMI (which I use for emergency console purposes). There's no option to disable serial on that page for me, unfortunately.

    For all intents and purposes, HDMI is still a "VGA" (video) console. If you installed from a serial memstick, that might explain what you are seeing. You may need to reinstall using a regular memstick.

  • Thanks! I'll give that a shot!
