# This file specifies various information about terminals on the system.
# It is used by several different programs. Common entries for the
# various columns include:
#
# name The name of the terminal device.
#
# getty The program to start running on the terminal. Typically a
# getty program, as the name implies. Other common entries
# include none, when no getty is needed, and xdm, to start the
# X Window System.
#
# type The initial terminal type for this port. For hardwired
# terminal lines, this will contain the type of terminal used.
# For virtual consoles, the correct type is cons25. Other
# common values include network for network connections on
# pseudo-terminals, dialup for incoming modem ports, and unknown
# when the terminal type cannot be predetermined.
#
# status Must be on or off. If on, init will run the getty program on
# the specified port. If the word "secure" appears, this tty
# allows root login.
#
# name getty type status comments
#
# If console is marked "insecure", then init will ask for the root password
# when going to single-user mode.
