# 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 typically xterm.
#      Other common values include 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.
console	none				unknown	off secure

Switch the default terminal emulation style to xterm for most platforms. Right now syscons(4) uses a cons25-style terminal emulator. The disadvantages of that are: - Little compatibility with embedded devices with serial interfaces. - Bad bandwidth efficiency, mainly because of the lack of scrolling regions. - A very hard transition path to support for modern character sets like UTF-8. Our terminal emulation library, libteken, has been supporting xterm-style terminal emulation for months, so flip the switch and make everyone use an xterm-style console driver. I still have to enable this on i386. Right now pc98 and i386 share the same /etc/ttys file. I'm not going to switch pc98, because it uses its own Kanji-capable cons25 emulator. IMPORTANT: What to do if things go wrong (i.e. graphical artifacts): - Run the application inside script(1), try to reduce the problem and send me the log file. - In the mean time, you can run `vidcontrol -T cons25' and `export TERM=cons25' so you can run applications the same way you did before. You can also build your kernel with `options TEKEN_CONS25' to make all virtual terminals use the cons25 emulator by default.

Remove the reference to pseudo-terminals from the description. Pseudo-terminals are no longer listed in this file, since the utmpx implementation doesn't depend on ttyslot(). 2011-03-30 08:22:29 +00:00			`# Other common values include dialup for incoming modem ports, and`

Change the terminal type/class for enabled serial lines to 3wire. This allows us to change the uart(4) driver to not hardcode specific line settings for the serial console. A terminal type of 3wire makes sure the console still works when no DCD signal is present, which preserves behviour. When it is known that the terminal server (or DCE in general) provides DCD, a terminal type/class of std can be used. This has the effect of being logged out when one disconnects from the console -- improving security overall. Likewise, when uart(4) does not fixate the baudrate, one can change the terminal type/class to set a specific baudrate. An operator can use this to change the console speed mid-flight, without needing a reboot. Of course it helps in this respect if and when the firmware can be configured from the OS. The above mentioned capabilities depend on uart(4) being changed, which is to happen next. 2014-03-09 21:06:22 +00:00			`ttyu0 "/usr/libexec/getty 3wire" vt100 on secure`
Add entries for uart based serial ports. All the serial ports on mips so far are uart subclasses. Also, turn uart0 on by default. 2008-10-12 06:58:03 +00:00			`ttyu1 "/usr/libexec/getty std.115200" dialup off secure`
