Data written to it disappears 26 and there is never any data to be read. 27 28config PORT_CHAN 29 bool "port channel support" 30 help 31 This option enables support for attaching UML consoles and serial 32 lines to host portals. They may be accessed with 'telnet <host> 33 <port number>'. Any number of consoles and serial lines may be 34 attached to a single portal, although what UML device you get when 35 you telnet to that portal will be unpredictable. 36 It is safe to say 'Y' here. 37 38config PTY_CHAN 39 bool "pty channel support" 40 help 41 This option enables support for attaching UML consoles and serial 42 lines to host pseudo-terminals. Access to both traditional 43 pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled 44 with this option. The assignment of UML devices to host devices 45 will be announced in the kernel message log. 46 It is safe to say 'Y' here. 47 48config TTY_CHAN 49 bool "tty channel support" 50 help 51 This option enables support for attaching UML consoles and serial 52 lines to host terminals. Access to both virtual consoles 53 (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and 54 /dev/pts/*) are controlled by this option. 55 It is safe to say 'Y' here. 56 57config XTERM_CHAN 58 bool "xterm channel support" 59 help 60 This option enables support for attaching UML consoles and serial 61 lines to xterms. Each UML device so assigned will be brought up in 62 its own xterm. 63 It is safe to say 'Y' here. 64 65config NOCONFIG_CHAN 66 bool 67 default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN) 68 69config CON_ZERO_CHAN 70 string "Default main console channel initialization" 71 default "fd:0,fd:1" 72 help 73 This is the string describing the channel to which the main console 74 will be attached by default. This value can be overridden from the 75 command line. The default value is "fd:0,fd:1", which attaches the 76 main console to stdin and stdout. 77 It is safe to leave this unchanged. 78 79config CON_CHAN 80 string "Default console channel initialization" 81 default "xterm" 82 help 83 This is the string describing the channel to which all consoles 84 except the main console will be attached by default. This value can 85 be overridden from the command line. The default value is "xterm", 86 which brings them up in xterms. 87 It is safe to leave this unchanged, although you may wish to change 88 this if you expect the UML that you build to be run in environments 89 which don't have X or xterm available. 90 91config SSL_CHAN 92 string "Default serial line channel initialization" 93 default "pty" 94 help 95 This is the string describing the channel to which the serial lines 96 will be attached by default. This value can be overridden from the 97 command line. The default value is "pty", which attaches them to 98 traditional pseudo-terminals. 99 It is safe to leave this unchanged, although you may wish to change 100 this if you expect the UML that you build to be run in environments 101 which don't have a set of /dev/pty* devices. 102 103config UML_SOUND 104 tristate "Sound support" 105 help 106 This option enables UML sound support. If enabled, it will pull in 107 soundcore and the UML hostaudio relay, which acts as a intermediary 108 between the host's dsp and mixer devices and the UML sound system. 109 It is safe to say 'Y' here. 110 111config SOUND 112 tristate 113 default UML_SOUND 114 115config SOUND_OSS_CORE 116 bool 117 default UML_SOUND 118 119config HOSTAUDIO 120 tristate 121 default UML_SOUND 122 123endmenu 124
