As mentioned last week, a new family/pin code selector program has installed in
the DIO procedure. It has a feature to add/change family/pin codes in the
database so you can help with the F/P maintenance. To use this feature type ADD
to the DIO_COMMAND prompt. The system will repeatedly prompt for a device name,
a vendor name, and the 3 F/P codes. As many may be input as you like.
Most of the devices will only need a primary F/P code. You can enter 0 (or
simply return) for the secondary and Unipak F/P codes unless the DIO chart
says otherwise.

The values appearing in brackets ([]'s) are default values which will be used if
nothing is input for the parameter. Typing 0's for all 3 F/P codes will cause
the program to ignore the entry. A null device name terminates the session
and installs the changes. F/P codes are not sent to the DIO by the ADD
command.

If you type a device/vendor combination that is already in the F/P tables, it'll
print out the old entry above the new entry and ask if you want to R(eplace) 
the old with the new, D(elete) the old one or Q(uit) to ignore the new entry.

The primary F/P code will be sent to the DIO first. If the DIO rejects it,
the secondary (if any) will be sent. If the DIO rejects that, an error message
will be displayed. The Unipak F/P code will only be sent if the program
knows it's running the Model 29 with a Unipak installed and the Unipak code
is not 0.
