# control-chars command

The control-chars command enables or
disables the entering of control characters at input, depending on
the option specified.

Under default conditions, nonediting control characters
are accepted by standard input commands. By doing control-chars
(f, these characters are ignored.

The settings of
this option are sent up and down levels for the current port.

The control-chars setting may be temporarily overwritten
in a BASIC program with the inputctrl statement.

Note: This setting does not affect the standard TCL stacker since
it utilizes all control keys for editing.

## Syntax

control-chars {(options}
```

## Parameter(s)

| options | f | Disables control character input. |
| --- | --- | --- |
| n | Enables control character input. This is the default. | |
