temporarily disable tty login


Hello,

I need to be able to have normal use of the serial port, but currently the terminal login is interfering with my program. Anyone know how to quickly and temporarily disable the serial login? Thanks,
-Heber

You are not telling us your distro, so it is more difficult to help you.

If your distro has the file /etc/inittab then find the entry that refers to whatever is respawning the getty process for ttyx (your serial port) is, and comment it out.

Then you'll either have to reboot, or kill the getty process for the serial port you do not want a login manager sitting on. You can't just kill it without first editing /etc/inittab because otherwise it'll just be respawned.

If you are using a recent ubuntu, take a look in /etc/event.d/ttyx

Thank you! For my debian build there certainly is a /etc/inittab file. I never could find what respawned it every time I killed it.
