  4	bool "stderr console"
  5	default y
  6	help
  7	  console driver which dumps all printk messages to stderr.

 13config SSL
 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.
 24
 25config 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
 32config 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
 42config 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
 52config 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
 61config 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
 69config NOCONFIG_CHAN
 70	bool
 71	default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
 72
 73config 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
 83config 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
 95config 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
107config 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.
114
