Create a Port an d IOtwio 
Create a port and two messages for the port. Use one of the
messages for the timer.device, the other for the console.device 
(creating both messages for the one port).

The WaitPort(yourPort) and see what arrived:
msg= GetMsg(yourPort);
if (msg==timerMsg) {
   ... timer stuff ...
}
else
if (msg==consoleMsg) {
   ... keystuff ...
}
else {
   ... curse and wait for another message ...
}
