Despite whatever baud rate is set in the settings (System->Advanced->Admin Access), successful serial connections only work with the default of 115200/8/N/1. Any other settings will appear garbled. Pictures are attached showing the issue.

Hardware:
Netgate 6100

Firmware Version:
24.11-RELEASE (amd64)

I confirmed that this error happens for Netgate 3100 too. I changed it to 9600, but it can still be connected with 115200 baud rate only.

The "password protect the console menu" is in use.

confirmed serial speed is not respected once changed, XG-7100 on 25.07.r.20250715.1733

Has anyone tried this on a non-EFI device to see if it works there?

This may only affect EFI consoles as they are different/special in this way. Though there are possibly a couple contributing factors.

• /boot/loader.conf.lua has a hardcoded line declaring comconsole_speed="115200" but changing that doesn't seem to have any effect on the EFI console speed
• The lines in /boot.config and /boot/loader.conf are updated with the appropriate speed
• We may need to set efi_com_speed to match the desired speed, though in my limited testing that didn't appear to have any effect on its own either
• In each case no matter what I set, this sysctl value was unchanged: hw.uart.console="io:1016,br:115200"
  • Setting that manually in /boot/loader.conf.local to the desired speed did work.
  • Don't just use that exact value, copy the current value and adjust the speed because different devices will have different addresses/console types there.

Tested with non-EFI, but nothing changed, and still working with 115200 baudrate

tested with a 5100 installed booting BIOS with 25.07 and the serial speed setting is retained in the web interface but still only able to connect using 115200
