have a 'flag' that you put 1 after the port reading is successful for the
2nd key being pushed. add a routine right after the check for the 2nd key so
that if the flag is 1 it exits so it doesnt fire again. then add code that
if the 2nd key wasn't pushed it changes it to a 0. this will make it appear
that the key is pressed and then it wont fire til it is released and pressed
again.
