Oh, I retried it and DosDevIOCtl returned error 22! Rechecking the dox (I
WANT paper!), I realized that this IOCtl don't work in a PM window!

In case Fullscreen is OK for you:

int kbhit(HFILE h)
{
    USHORT para = 0;
    ULONG  para_len = sizeof(para);
    KBDKEYINFO  data;
    ULONG  data_len = sizeof(data);
    APIRET rc;

    rc = DosDevIOCtl( h, 4, 0x75,
            ¶, para_len, ¶_len,
            &data, data_len, &data_len );

    return para;
}

IOCtl 4/0x74: 
{
para = 1;
return (data.chChar ? : data.chChar : data.chScan&0x0100);
}

I also tried IOCtl 4/0x51 but it switches my keyboard to this binary mode
in the whole PM. Thank god, Ive got a mouse...
