- * [ -clrtabs [ tab1 tab2 tab3 ... ] (tabn = 1-160)
- * [ -regtabs [1-160] ]

- *
- * Semantics:
- *
- * Setterm writes to standard output a character string that will invoke the
- * specified terminal capabilities. Where possibile termcap is consulted to
- * find the string to use. Some options however do not correspond to a
- * termcap 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.
