The User-Mode Linux environment allows you to create virtual serial
|
|
lines on the UML that are usually made to show up on the host as
|
|
ttys or ptys.
|
|
|
|
See <http://user-mode-linux.sourceforge.net/old/input.html> for more
|
|
information and command line examples of how to use this facility.
|
|
|

Unless you have a specific reason for disabling this, say Y.

This option enables support for attaching UML consoles and serial

lines to host portals. They may be accessed with 'telnet <host>
|
|
<port number>'. Any number of consoles and serial lines may be
|
|
attached to a single portal, although what UML device you get when

you telnet to that portal will be unpredictable.

This option enables support for attaching UML consoles and serial

pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled

This is the string describing the channel to which all consoles

This User-Mode Linux network driver uses multi-message send

This driver provides tap, raw, gre and l2tpv3 network transports.
