@CHIP-RTOS C Library V2.00 - BIOS API


BIOS_Set_Focus_Hotkey

Set the stdio focus key.

void BIOS_Set_Focus_Hotkey ( unsigned char hotkey );

Parameters

hotkey

New focus key code in range:   [ 0 .. 254 ]

Return Value

-- none --

Comments

The default hot key is CTRL-F, ASCII 6.

If the focus key is set to zero, the switching of stdio from the console is disabled.

At runtime, the hot key (e.g. Ctrl-F) toggles the stdio between three modes:

    Stdio: Shell   -   Focus set to command shell
    Stdio: User   -   Focus set to applications
    Stdio: Both   -   Command shell and applications

The focus key is not usable by the command shell or DOS executable.
