-\title{{\bf Linux Allocated Devices}}
-\author{Maintained by H. Peter Anvin $<$hpa@zytor.com$>$}
-\date{Last revised: August 10, 1998}
-\maketitle

-\noindent
-This list is the Linux Device List, the official registry of allocated
-device numbers and {\file /dev} directory nodes for the Linux
-operating system.
-
-The latest version of this list is included with the Linux kernel
-sources in \LaTeX\ and ASCII form. It is also available separately
-from {\url ftp://ftp.kernel.org/pub/linux/docs/device-list/}. In case
-of discrepancy between the text and \LaTeX\ versions, the \LaTeX\
-version is authoritative.
-
-This document is included by reference into the Linux Filesystem
-Standard (FSSTND). The FSSTND is available from
-{\url ftp://tsx-11.mit.edu/pub/linux/docs/linux-standards/fsstnd/}.
-
-Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
-platform only. Allocations marked (68k/Atari) apply to Linux/68k on
-the Atari platform only.
-
-This document is in the public domain. The author requests, however,
-that semantically altered versions are not distributed without
-permission of the author, assuming the author can be contacted without
-an unreasonable effort.
-
-In particular, please don't sent patches for this list to Linus, at
-least not without contacting me first.
-
-I do not have any information about these devices beyond what appears
-on this list. Any such information requests will be deleted without
-reply.
-
-\section{How to submit a device entry}
-
-To have a major number allocated, or a minor number in situations
-where that applies (e.g. busmice), please contact me with the
-appropriate device information. Also, if you have additional
-information regarding any of the devices listed below, or if I have
-made a mistake, I would greatly appreciate a note.
-
-I do, however, make two requests about the nature of your report.
-This is necessary for me to be able to keep this list up to date and
-correct in a timely manner. First of all, {\em please\/} include the
-word ``device'' in the subject so your mail won't accidentally get
-buried! I receive hundreds of email messages a day, so mail sent with
-other subjects may very well get lost in the avalanche.
-
-Second, please include a description of the device {\em in the same
-format as this list\/}. The reason for this is that it is the only
-way I have found to ensure I have all the requisite information to
-publish your device and avoid conflicts.
-
-Your cooperation is appreciated.

-\section{Additional /dev directory entries}
-
-This section details additional entries that should or may exist in the
-{\file /dev} directory. It is preferred that symbolic links use the
-same form (absolute or relative) as is indicated here. Links are
-classified as {\em hard\/} or {\em symbolic\/} depending on the
-preferred type of link; if possible, the indicated type of link should
-be used.
-
-\subsection{Compulsory links}
-
-These links should exist on all systems:
-
-\begin{nodelist}
-\link{/dev/fd}{/proc/self/fd}{symbolic}{File descriptors}
-\link{/dev/stdin}{fd/0}{symbolic}{Standard input file descriptor}
-\link{/dev/stdout}{fd/1}{symbolic}{Standard output file descriptor}
-\link{/dev/stderr}{fd/2}{symbolic}{Standard error file descriptor}
-\link{/dev/nfsd}{socksys}{symbolic}{Required by iBCS-2}
-\link{/dev/X0R}{null}{symbolic}{Required by iBCS-2}
-\end{nodelist}
-
-\noindent
-Note: The last device is: $<$letter {\tt X}$>$-$<$digit {\tt
-0}$>$-$<$letter {\tt R}$>$.
-
-\subsection{Recommended links}
-
-It is recommended that these links exist on all systems:
-
-\begin{nodelist}
-\link{/dev/core}{/proc/kcore}{symbolic}{Backward compatibility}
-\link{/dev/ramdisk}{ram0}{symbolic}{Backward compatibility}
-\link{/dev/ftape}{qft0}{symbolic}{Backward compatibility}
-\link{/dev/bttv0}{video0}{symbolic}{Backward compatibility}
-\link{/dev/radio}{radio0}{symbolic}{Backward compatibility}
-\link{/dev/scd?}{sr?}{hard}{Alternate name for CD-ROMs}
-\end{nodelist}
-
-\subsection{Locally defined links}
-
-The following links may be established locally to conform to the
-configuration of the system. This is merely a tabulation of existing
-practice, and does not constitute a recommendation. However, if they
-exist, they should have the following uses.
-
-\begin{nodelist}
-\vlink{/dev/mouse}{mouse port}{symbolic}{Current mouse device}
-\vlink{/dev/tape}{tape device}{symbolic}{Current tape device}
-\vlink{/dev/cdrom}{CD-ROM device}{symbolic}{Current CD-ROM device}
-\vlink{/dev/cdwriter}{CD-writer}{symbolic}{Current CD-writer device}
-\vlink{/dev/scanner}{scanner device}{symbolic}{Current scanner device}
-\vlink{/dev/modem}{modem port}{symbolic}{Current dialout device}
-\vlink{/dev/root}{root device}{symbolic}{Current root filesystem}
-\vlink{/dev/swap}{swap device}{symbolic}{Current swap device}
-\end{nodelist}
-
-\noindent
-{\file /dev/modem} should not be used for a modem which supports
-dialin as well as dialout, as it tends to cause lock file problems.
-If it exists, {\file /dev/modem} should point to the appropriate
-primary TTY device (the use of the alternate callout devices is
-deprecated.)
-
-For SCSI devices, {\file /dev/tape} and {\file /dev/cdrom} should
-point to the ``cooked'' devices ({\file /dev/st*} and {\file
-/dev/sr*}, respectively), whereas {\file /dev/cdwriter} and {\file
-/dev/scanner} should point to the appropriate generic SCSI devices
-({\file /dev/sg*}).
-
-{\file /dev/mouse} may point to a primary serial TTY device, a
-hardware mouse device, or a socket for a mouse driver program
-(e.g. {\file /dev/gpmdata}).
-
-\subsection{Sockets and pipes}
-
-Non-transient sockets or named pipes may exist in {\file /dev}.
-Common entries are:
-
-\begin{nodelist}
-\node{/dev/printer}{socket}{{\file lpd} local socket}
-\node{/dev/log}{socket}{{\file syslog} local socket}
-\node{/dev/gpmdata}{socket}{{\file gpm} mouse multiplexer}
-\end{nodelist}
-
-\section{Terminal devices}
-
-Terminal, or TTY devices are a special class of character devices. A
-terminal device is any device that could act as a controlling terminal
-for a session; this includes virtual consoles, serial ports, and
-pseudoterminals (PTYs).
-
-All terminal devices share a common set of capabilities known as line
-diciplines; these include the common terminal line dicipline as well
-as SLIP and PPP modes.
-
-All terminal devices are named similarly; this section explains the
-naming and use of the various types of TTYs. Note that the naming
-conventions include several historical warts; some of these are
-Linux-specific, some were inherited from other systems, and some
-reflect Linux outgrowing a borrowed convention.
-
-A hash mark ($\#$) in a device name is in all cases used here to
-indicate a decimal number without leading zeroes.
-
-\subsection{Virtual consoles and the console device}
-
-Virtual consoles are full-screen terminal displays on the system video
-monitor. Virtual consoles are named {\file /dev/tty$\#$}, with
-numbering starting at {\file /dev/tty1}; {\file /dev/tty0} is the
-current virtual console. {\file /dev/tty0} is the device that should
-be used to access the system video card on those architectures for
-which the frame buffer devices ({\file /dev/fb*}) are not applicable.
-Do not use {\file /dev/console} for this purpose.
-
-The {\em console device\/}, {\file /dev/console}, is the device to
-which system messages should be sent, and on which logins should be
-permitted in single-user mode. Starting with Linux 2.1.71, {\file
-/dev/console} is managed by the kernel; for previous versions it
-should be a symbolic link to either {\file /dev/tty0}, a specific
-virtual console such as {\file /dev/tty1}, or to a serial port primary
-({\file tty*}, not {\file cu*}) device, depending on the configuration
-of the system.
-
-\subsection{Serial ports}
-
-Serial ports are RS-232 serial ports and any device which simulates
-one, either in hardware (such as internal modems) or in software (such
-as the ISDN driver.) Under Linux, each serial ports has two device
-names, the primary or callin device and the alternate or callout one.
-Each kind of device is indicated by a different letter. For any
-letter $X$, the names of the devices are {\file /dev/tty${X\#}$} and
-{\file /dev/cu${x\#}$}, respectively; for historical reasons, {\file
-/dev/ttyS$\#$} and {\file /dev/ttyC$\#$} correspond to {\file
-/dev/cua$\#$} and {\file /dev/cub$\#$}. In the future, it should be
-expected that multiple letters will be used; all letters will be upper
-case for the {\file tty} device (e.g. {\file /dev/ttyDP$\#$} and lower
-case for the {\file cu} device (e.g. {\file /dev/cudp$\#$}.
-
-The use of the callout devices is deprecated.
-
-The names {\file /dev/ttyQ$\#$} and {\file /dev/cuq$\#$} are reserved
-for local use.
-
-The alternate devices provide for kernel-based exclusion and somewhat
-different defaults than the primary devices. Their main purpose is to
-allow the use of serial ports with programs with no inherent or broken
-support for serial ports. Their use is deprecated, and they may be
-removed from a future version of Linux.
-
-Arbitration of serial ports is provided by the use of lock files with
-the names {\file /var/lock/LCK..tty${X\#}$}. The contents of the lock
-file should be the PID of the locking process as an ASCII number.
-
-It is common practice to install links such as {\file /dev/modem\/}
-which point to serial ports. In order to ensure proper locking in the
-presence of these links, it is recommended that software chase
-symlinks and lock all possible names; additionally, it is recommended
-that a lock file be installed with the corresponding alternate
-device. In order to avoid deadlocks, it is recommended that the locks
-are acquired in the following order, and released in the reverse:
-\begin{itemize}
-\item{The symbolic link name, if any ({\file /var/lock/LCK..modem})}
-\item{The {\file tty} name ({\file /var/lock/LCK..ttyS2})}
-\item{The alternate device name ({\file /var/lock/LCK..cua2})}
-\end{itemize}
-In the case of nested symbolic links, the lock files should be
-installed in the order the symlinks are resolved.
-
-Under no circumstances should an application hold a lock while waiting
-for another to be released. In addition, applications which attempt
-to create lock files for the corresponding alternate device names
-should take into account the possibility of being used on a non-serial
-port TTY, for which no alternate device would exist.
-
-\subsection{Pseudoterminals (PTYs)}
-
-Pseudoterminals, or PTYs, are used to create login sessions or provide
-other capabilities requiring a TTY line dicipline (including SLIP or
-PPP capability) to arbitrary data-generation processes. Each PTY has
-a {\em master\/} side, named {\file /dev/pty[p-za-e][0-9a-f]\/}, and a
-{\em slave\/} side, named {\file /dev/tty[p-za-e][0-9a-f]\/}. The
-kernel arbitrates the use of PTYs by allowing each master side to be
-opened only once.
-
-Once the master side has been opened, the corresponding slave device
-can be used in the same manner as any TTY device. The master and
-slave devices are connected by the kernel, generating the equivalent
-of a bidirectional pipe with TTY capabilities.
-
-Recent versions of the Linux kernels and GNU libc contain support for
-the System V/Unix98 naming scheme for PTYs, which assigns a common
-device {\file /dev/ptmx\/} to all the masters (opening it will
-automatically give you a previously unassigned PTY) and a subdirectory
-{\file /dev/pts\/} for the slaves; the slaves are named with decimal
-integers ({\file /dev/pts/$\#$\/} in our notation). This removes the
