wsconscfg - configure virtual terminals on a wscons display
wsconscfg [-dFkm] [-e emul] [-f ctldev] [-t type] index
The wsconscfg tool allows for the creation and removal of virtual termi- nals 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 (current- ly 11, allowing for 12 virtual terminals on a display). In keyboard con- figuration mode (see -k, below), it specifies the wskbd(4) device to at- tach 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: -d Delete the specified terminal. Any specified terminal that is currently open by a program will not be deleted unless the -F op- tion is also given. Terminals used by the operating system con- sole or a graphics program (X server) cannot be deleted. With the -k flag, the keyboard specified by index will be detached from the wscons display. With the -m flag, the multiplexor specified by index will be detached from the wscons display. -e emul 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. -F Force deletion of a terminal, keyboard, or multiplexor, even if it is in use by a userspace program. -f ctldev Specify the control device of the wscons display to operate on. The default is /dev/ttyCcfg. -k Do keyboard related operations instead of virtual screen confi- guration. 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. -m Do multiplexor related operations instead of virtual screen con- figuration. Without other flags, a multiplexor will be attached to the display device. -t type Specify a screen type to use. Screen types refer to display for- mat, 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).) # wsconscfg -t 80x50 -e vt100 1 Connect the first unconnected keyboard to the display: # wsconscfg -k
wscons(4), wskbd(4), wsconsctl(8), wsfontload(8)
The wsconscfg program first appeared in OpenBSD 2.8.
There should be an easy way to get a list of the screen types available on a display, and of the emulations supported by the kernel. MirOS BSD #10-current January 12, 1999 1
