A83: Reading keyboard port



Hello,
 
I am new to assembly programming, but have been able to use B_Call GetKey to get a character typed into the calculator.  But, this waits for a ckey to be pressed.  Is there a way to query the keyboard port to see if a key has been pressed, so that my code can keep executing in a loop until input arrives?
 
Regards,

Scot Watson
