configure virtual terminals on a wscons
wsconscfg tool allows for the creation
and removal of virtual terminals on display devices controlled by the wscons
terminal framework, as long as the underlying display hardware driver
supports multiple screens. Furthermore, it controls the assignment of
keyboards to displays.
The index argument specifies which virtual
terminal is to be configured. Valid numbers range from 0 to an
implementation-specified value (currently 11, allowing for 12 virtual
terminals on a display). In keyboard configuration mode (see
-k, below), it specifies the
device to attach or detach. Without further option arguments, a virtual
terminal is created with implementation specific properties and a default
terminal emulation variant selected at kernel compile time.
The options are as follows:
- Delete the specified terminal. Any specified terminal that is currently
open by a program will not be deleted unless the
-Foption is also given. Terminals used by the operating system console or a graphics program (X server) cannot be deleted. With the
-kflag, the keyboard specified by index will be detached from the wscons display. With the
-mflag, the multiplexor specified by index will be detached from the wscons display.
- Specify the terminal emulation to use for the virtual terminal. The set of available terminal emulations is determined at kernel compile time. See wscons(4) for details.
- Force deletion of a terminal, keyboard, or multiplexor, even if it is in use by a userspace program.
- Specify the control device of the wscons display to operate on. The default is /dev/ttyCcfg.
- Do keyboard related operations instead of virtual screen configuration. Without other flags, a keyboard will be attached to the display device. The index argument can be omitted: in that case the first free keyboard will be used.
- Do multiplexor related operations instead of virtual screen configuration. Without other flags, a multiplexor will be attached to the display device.
- Specify a screen type to use. Screen types refer to display format, color depth, and other low-level display properties. Valid type arguments are defined by the underlying display device driver.
Configure screen 1 (i.e., the second) for type “80x50” and VT100 terminal emulation. (Note: “80x50” is a screen type offered by the vga(4) display driver. In this particular case, an 8x8-font must be loaded beforehand to make the screen useful. See wsfontload(8).)
Connect the first unconnected keyboard to the display:
# wsconscfg -k
