Table 3-1 Notes:
1.
The Serial Remote Interface uses a protocol and command set very similar to the Computer Interface port. Refer to that portion
of this section for programming reference. Additionally, the Serial Remote port includes the following command:

Set Control Mode. If the CHPA is in either Remote or CIF mode, the Serial
Remote port may shift control between Remote and CIF. To specify Remote,
follow the command with the number 0 (ASCII 30 Hex. 48 Dec.); to specify CIF,
use the number 1 (ASCII 31 Hex.49 Dec.).
