<dt><code>CONFIG_NXCONSOLE_NXKBDIN</code>:
<dd>Take input from the NX keyboard input callback.
By default, keyboard input is taken from stdin (<code>/dev/console</code>).
If this option is set, then the interface<code>nxcon_kdbin()</code> is enabled.
That interface may be driven by window callback functions so that keyboard input <i>only</i> goes to the top window.

<dd>If <code>CONFIG_NXCONSOLE_NXKBDIN</code> is enabled, then this value may be used to
define the size of the per-window keyboar input buffer. Default: 16
