该程序可以实现SCO OpenServer在硬件检测完毕后自动Numlock

lockkeys编译方法：cc -o lockkeys lockkeys.c

实现步骤：

1、将lockkeys执行程序拷贝到/etc目录下，并赋予执行权限；
2、把numlock.init.string中的代码加入到/etc/inittab文件中指令行的第一行。

numlock.init.string代码内容：

snum::sysinit:/etc/lockkeys numlock on < /dev/console >/dev/console 2>&1

lockkeys源代码：

/*
* Program to control the console lock keys states
*
* Build with "cc -o lockkeys lockkeys.c"
*/

int argc;
char *argv[];

        char c;
        int function, key;

        if ( argc != 3 ) {
                fprintf( stderr, "Usage: lockkeys key on | off | toggle
" );
                exit( 1 );
        }

        if ( !strcmp( argv[2], "off" ))
                function=0;
        else if ( !strcmp( argv[2], "on" ))
                function=1;
        else if ( !strcmp( argv[2], "toggle" ))
                function=2;
        else {
                fprintf( stderr,
                        "lockkeys: function must be on, off, or toggle

                exit( 1 );
        }

        if ( !strcmp( argv[1], "numlock" ))
                key=NUMLOCK;
        else if ( !strcmp( argv[1], "capslock" ))
                key=CAPSLOCK;
        else if ( !strcmp( argv[1], "scrolllock" ))
                key=SCROLLLOCK;
        else {
                fprintf( stderr,
                        "lockkeys: key must be numlock, capslock, or scrolllock
" );
                exit( 1 );
        }

        if ( ioctl( RDFD, KDGETLED, &c ) != 0 ) {
                perror( "lockkeys: can't get current lock state" );
                exit( 2 );
        }
        if ( function == 0 )
                c &= ~key;
        else if ( function == 1 )
                c |=  key;
        else
                c ^=  key;
        if ( ioctl( RDFD, KDSETLED, c ) != 0 ) {
                perror( "lockkeys: error setting lock state" );
                exit( 2 );
        }
        exit( 0 );
}
