  14         bool "Virtual serial line"
  15         help
  16           The User-Mode Linux environment allows you to create virtual serial
  17           lines on the UML that are usually made to show up on the host as
  18           ttys or ptys.
  19
  20           See <http://user-mode-linux.sourceforge.net/old/input.html> for more
  21           information and command line examples of how to use this facility.
  22
  23           Unless you have a specific reason for disabling this, say Y.

  25 config NULL_CHAN
  26         bool "null channel support"
  27         help
  28           This option enables support for attaching UML consoles and serial
  29           lines to a device similar to /dev/null.  Data written to it disappears
  30           and there is never any data to be read.
  31
  32 config PORT_CHAN
  33         bool "port channel support"
  34         help
  35           This option enables support for attaching UML consoles and serial
  36           lines to host portals.  They may be accessed with 'telnet <host>
  37           <port number>'.  Any number of consoles and serial lines may be
  38           attached to a single portal, although what UML device you get when
  39           you telnet to that portal will be unpredictable.
  40           It is safe to say 'Y' here.
  41
  42 config PTY_CHAN
  43         bool "pty channel support"
  44         help
  45           This option enables support for attaching UML consoles and serial
  46           lines to host pseudo-terminals.  Access to both traditional
  47           pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
  48           with this option.  The assignment of UML devices to host devices
  49           will be announced in the kernel message log.
  50           It is safe to say 'Y' here.
  51
  52 config TTY_CHAN
  53         bool "tty channel support"
  54         help
  55           This option enables support for attaching UML consoles and serial
  56           lines to host terminals.  Access to both virtual consoles
  57           (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
  58           /dev/pts/*) are controlled by this option.
  59           It is safe to say 'Y' here.
  60
  61 config XTERM_CHAN
  62         bool "xterm channel support"
  63         help
  64           This option enables support for attaching UML consoles and serial
  65           lines to xterms.  Each UML device so assigned will be brought up in
  66           its own xterm.
  67           It is safe to say 'Y' here.
  68
  69 config NOCONFIG_CHAN

  71         default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)

  73 config CON_ZERO_CHAN
  74         string "Default main console channel initialization"
  75         default "fd:0,fd:1"
  76         help
  77           This is the string describing the channel to which the main console
  78           will be attached by default.  This value can be overridden from the
  79           command line.  The default value is "fd:0,fd:1", which attaches the
  80           main console to stdin and stdout.
  81           It is safe to leave this unchanged.
  82
  83 config CON_CHAN
  84         string "Default console channel initialization"
  85         default "xterm"
  86         help
  87           This is the string describing the channel to which all consoles
  88           except the main console will be attached by default.  This value can
  89           be overridden from the command line.  The default value is "xterm",
  90           which brings them up in xterms.
  91           It is safe to leave this unchanged, although you may wish to change
  92           this if you expect the UML that you build to be run in environments
  93           which don't have X or xterm available.
  94
  95 config SSL_CHAN
  96         string "Default serial line channel initialization"
  97         default "pty"
  98         help
  99           This is the string describing the channel to which the serial lines
 100           will be attached by default.  This value can be overridden from the
 101           command line.  The default value is "pty", which attaches them to
 102           traditional pseudo-terminals.
 103           It is safe to leave this unchanged, although you may wish to change
 104           this if you expect the UML that you build to be run in environments
 105           which don't have a set of /dev/pty* devices.
 106
 107 config UML_SOUND
 108         tristate "Sound support"
 109         help
 110           This option enables UML sound support.  If enabled, it will pull in
 111           soundcore and the UML hostaudio relay, which acts as a intermediary
 112           between the host's dsp and mixer devices and the UML sound system.
 113           It is safe to say 'Y' here.
