WORD 6
260: V7657	The CPU will accept the setup values when a 'setup complete' flag is written to this V-memory location. For the 260 this flag is a value of K0500, representing the available port. 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.
