After data entry, your program must refresh the watchdog timer by rewriting the I/O port 443 (hex) while simultaneously setting it. When you want to disable the watchdog timer, your program should read I/O port 443 (hex). The following example shows how you might program the watchdog timer in BASIC: Watchdog timer example program OUT &H443, data REM...
