allows modem Port D to process captions in Field 1, allows Port B to process text
articles in field 1, and enables Port C for extended data services.

captions in field 2, Port C is not actively controlling any data, and the Port D modem is online and is
controlling the extended data services.
4.6.4. Alter Port Active Maps

optional override parameter (‘O’) forces other control ports to relinquish control of the specified data
type.
