You can make it work either by waiting in select() or something
that will return when either a kbd or mouse event occurs, or
by polling.  In either case, hack MwSelect() in nanox/srvmain.c
or mwin/winmain.c to get your keyboard input.

What won't work is waiting in a select for your mouse input,
and somehow getting your keyboard input through another
method.  When you press a key, the select won't return.  So
you'll have to devise another method.  The MSDOS version,
for instance, continually polls both kbd and mouse. (that's
what the kbd_poll entry point is for, usually unused in Linux)
