The CPU will accept the setup values when a 'setup complete' flag is written to this V-memory location. For the 450 this flag is a value of K5555, representing the 4 available ports, and a value of K0500 for the 250 and 350 CPUs. When the CPU checks this value, it will change the '5' to an 'A' if the port settings have been accepted, or an 'E' if there was an error. |
