Yes. IBM changed this in OS/2 2.10! Earlier there were NO problem to read
the keyboard in one thread, while another thread asks if eg. NumLock is
currently pressed.
But still working is low-level Device IO Code. So now, i'm using

    cRecords = KBD_READ_WAIT | 1;
    DosDevIOCtl(&kbci, &cRecords, KBD_READCHAR, IOCTL_KEYBOARD, _hfKbd);

in my keyboard read thread, which enables other threads to use KbdChar* calls.

Note: The above is code from my old 16bit app, so this is a 16bit DevIO call!!

Mario
