Serial Console Issue 23.7.5 -> 23.7.6

[rebuilder]

I am running two apu4d4 pcengines boards. These are used alternatively when opnsense versions
are introduced. I use minicom 2.8 running on an old 32 bit asus eee pc 900 (32 bit debian OS)
for the video terminal serial console.

Running 23.7.5 on one of the apu4d4 and minicom package works fine with the serial console
performing as expected. When the other apu4d4 is run with opnsense 23.7.6 the serial console
performs as expected (displays the boot process steps) until the boot process passes the
botton of the second hash line. At this point the display stops and does not show the log on steps.
Also anything typed  on the serial display is ignored. When running 192.168.1.1 on one of the lans
provides full and normal access. The system seems to be running normally with no obvious faults.

I'd like suggestions on how to diagnose this problem since the serial console is unusable. The
hardware is the same in both cases so it must be a software issue. I don't think it is the apu4d4
boards since they have performed well for a significant period of time.I don't think its the
minicom package since I have successfully used this on pcengines apu2 boards with no problems.

can you compare settings in System > Settings > Administration > Console

Thank you for the reply and apparent solution to the problem. Checking the
systems>settings>administration>console shows that all lines are identical
except for the line "USB based serial - use USB based serial ports" was checked
in my installation of 23.7.6 and not checked in 27.7.5. Removing the check
from this line in 27.7.6 restored the serial console to normal operation.
