+# This file specifies various information about terminals on the system.

+#
+# 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.
