|
|
*
|
|
* Semantics:
|
|
*
|
|
* Setterm writes to standard output a character string that will
|
|
* invoke the specified terminal capabilities. Where possibile
|
|
* terminfo is consulted to find the string to use. Some options
|
|
* however do not correspond to a terminfo capability. In this case if
|
|
* the terminal type is "con*", or "linux*" the string that invokes
|
|
* the specified capabilities on the PC Linux virtual console driver
|
|
* is output. Options that are not implemented by the terminal are
|
|
* ignored.
|
|
*
|
|
* The following options are non-obvious.
|
|
*
|
|
* -term can be used to override the TERM environment variable.
|
|
*
|
|
* -reset displays the terminal reset string, which typically resets the
|
|
* terminal to its power on state.
|
|
*
|
|
* -initialize displays the terminal initialization string, which typically
|
|
* sets the terminal's rendering options, and other attributes to the
|
|
* default values.
|
|
*
|
|
* -default sets the terminal's rendering options to the default values.
|
|
*
|
|
* -store stores the terminal's current rendering options as the default
|
|
* values. */
