I'm experiencing some problems with bioskey() 
excerpt from a help-file about it :

" COMMAND = 0
     Returns the next key pressed.  The value returned is a combination
     of the key's scan code in the high 8 bits and its ASCII code in
     the low 8 bits.

COMMAND = 1
     Checks the keyboard, returns zero if no key pressed, else the key.
     Does not dequeue the key from the keyboard buffer.  The value
     returned when a key was pressed is a combination of the key's scan
     code in the high 8 bits and its ASCII code in the low 8 bits. "

(and command = 10 is command = 0 for extended 101 keyboard, idem command =
11 is command = 1)

I tried with some code :

unsigned key;
  while (true) {
    key=bioskey(0);
    if (key!=0) {      
      putch(key);
    }
  }

I press 'p', it does nothing, idem for command=10 and command=11,
strange...
With command=1, it loops forever displaying a lot of 'p', that's normal,
but if I press an other key, it will keep displaying the first key pressed,
why ? 

Is there some predefined constant (like keys.h) to use with bioskey() ?
