LCDproc Looses Connection - Restarting service Fixes but goes down again shortly after

[ngr2001]

PFSense+ 24.11-RELEASE
LCDproc 0.12_2

LCDproc is working just fine with my CrystalFontz LCD, however after what appears to be only a few hours, LCDproc looses its connection and the LCD stops displaying data. If I restart the LCDproc services everything starts working again. A few hours later the service looses connection again and the LCD goes dead.

I use the following port.

USB COM port 1 (/dev/cuaUO)

I have a hunch that maybe resetting the firewall states breaks the LCDproc connection. I've been bouncing that a lot lately for some rule testing, perhaps this was self inflected. I will continue to monitor. I think the port is really tied to your specific hardware setup, but if it dies again ill give that a go for sure.

@ngr2001

it's the same physical port just a different kernel driver. From what I read tty is for dial-in devices and cua is for dial-out devices.

Well you learn something new each day.

I flipped it, still works, ill leave it your way and see how it goes.

thanks.

Firewall states wouldn't affect LCDProc since it's not a TCP connection, it's local serial.

You should definitely be using cuaU0 or a cuaU<n> port, though, not a TTY.

I have LCDProc going on two systems, one with a crystalfontz display and another with an adafruit LCD+Backpack setup. Both work great and never lose connection.
