Carriage Returns and Line Feeds

The user may choose to use carriage returns (CR) and line feeds (LF); they are appended to the
command/response. If both CR and LF are chosen, they will be appended in the order CR LF.
Be sure that the CIF port's setting matches the user's monitor and control computer settings—
mismatches in settings may result in the CHPA providing partial or unexpected responses.
To select CR, press the MENU button to select CIF CONFIGURATION; press the FUNCTION
button to select CR ENABLE. Use the arrow keys to select the desired choice (YES or NO).
To select LF, press the MENU button to select CIF CONFIGURATION; press the FUNCTION
button to select LF ENABLE. Use the arrow keys to select the desired choice (YES or NO).

Commands

Commands are sent from a computer to the CHPA. Refer to information given earlier in this
section for the proper formats for commands. There are four types of commands:
•
Query commands. These commands cause the CHPA to return information. The returned
bytes are called status bytes; they are described in detail later in this section. Refer to Table
3-7.
•
CHPA commands. These commands cause the CHPA to take some action. Refer to Table 3-
8.
•
Slow commands. A subset of CHPA commands, these commands may require several
seconds to complete. Refer to Table 3-9.
•
Interface commands. These commands invoke special interface features. Refer to Table 3-10.
A table for each command type is provided. The tables include the ASCII code associated with
the commands and its base 10 representation, and the command name and a description of the
