How to setup a Dumb Terminal using an Upstart script

Dumb Terminals can still be quite useful for some tasks.

Create a the file /etc/event.d/ttyS0 (Replace ttyS0 with whatever port you are connecting the dumb terminal to)

Paste this script into the file. Alter as required for your configuration.

# ttyS0 - getty  
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on runlevel 2
start on runlevel 3
start on runlevel 4
start on runlevel 5
start on stopped ttyS0  #restarts the terminal if it is exited or crashes

stop on shutdown

respawn
exec /sbin/getty 19200 ttyS0 vt100  
#change the communication speed, port number and protocol
#for your configuration.

One thing to note, if you turn on the terminal after the host computer boots up, it will take up to a minute for the login prompt to be displayed on the terminal, but it will show up.
