4c9e1385 JD |
13 | The User-Mode Linux environment allows you to create virtual serial |
14 | lines on the UML that are usually made to show up on the host as | |
15 | ttys or ptys. | |

0ba9d3f9 | 17 | See <http://user-mode-linux.sourceforge.net/old/input.html> for more |
4c9e1385 | 18 | information and command line examples of how to use this facility. |

24 | help | |
4c9e1385 JD |
25 | This option enables support for attaching UML consoles and serial |
26 | lines to a device similar to /dev/null. Data written to it disappears | |
27 | and there is never any data to be read. | |

31 | help | |
4c9e1385 JD |
32 | This option enables support for attaching UML consoles and serial |
33 | lines to host portals. They may be accessed with 'telnet <host> | |
34 | <port number>'. Any number of consoles and serial lines may be | |
35 | attached to a single portal, although what UML device you get when | |
36 | you telnet to that portal will be unpredictable. | |
37 | It is safe to say 'Y' here. | |

4c9e1385 JD |
42 | This option enables support for attaching UML consoles and serial |
43 | lines to host pseudo-terminals. Access to both traditional | |
44 | pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled | |
45 | with this option. The assignment of UML devices to host devices | |
46 | will be announced in the kernel message log. | |
47 | It is safe to say 'Y' here. | |

4c9e1385 JD |
52 | This option enables support for attaching UML consoles and serial |
53 | lines to host terminals. Access to both virtual consoles | |
54 | (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and | |
55 | /dev/pts/*) are controlled by this option. | |
56 | It is safe to say 'Y' here. | |

4c9e1385 JD |
74 | This is the string describing the channel to which the main console |
75 | will be attached by default. This value can be overridden from the | |
76 | command line. The default value is "fd:0,fd:1", which attaches the | |
77 | main console to stdin and stdout. | |

4c9e1385 JD |
84 | This is the string describing the channel to which all consoles |
85 | except the main console will be attached by default. This value can | |
86 | be overridden from the command line. The default value is "xterm", | |
87 | which brings them up in xterms. | |
88 | It is safe to leave this unchanged, although you may wish to change | |
89 | this if you expect the UML that you build to be run in environments | |
90 | which don't have X or xterm available. | |

96 | This is the string describing the channel to which the serial lines |
97 | will be attached by default. This value can be overridden from the | |
98 | command line. The default value is "pty", which attaches them to | |
99 | traditional pseudo-terminals. | |
100 | It is safe to leave this unchanged, although you may wish to change | |
101 | this if you expect the UML that you build to be run in environments | |
