Command Protocol

`çãã~åÇ=mêçíçÅçä

The PDS’s command protocol is compatible with GNU getopt parsing. Every parameter of the command has an option character associated with it. A <CR> carriage return (ASCII 13) terminates the command.

Note

The order of the option characters in the command does not matter.

Command example:

ITYPE -i 2 -t 1<CR>

Or

ITYPE -t 1 -i 2<CR>

`çãã~åÇ=oÉëéçåëÉë

A command response is sent after each command is processed. This response consists of the command, followed by the error code, a line feed <LF> and a special termination character (\x4).

When a command is successful, the error code is a 0 (eERR_OK), or some positive value.

When a command is not successful, the error code is a negative value. A preliminary list of the error codes is included. Refer to the “Error Codes” section on page 134 for details.

Command response example:

ITYPE -e 0<LF> </x4>

nìÉêó=léíáçåë

Query type options are available for the commands. The order of precedence for processing query option arguments is help (--help), query (-?), and list (--list). If more than one query option is sent in a command, the option with the highest precedence is processed, and any others are ignored.

Help Query — Commands have a “help” query option associated with them, (--help). This query lists all option flags and parameters for the command in the following format:

Help option example:

IBRT --help<CR>

Response:

f_oq

Description: Input Brightness Adjust

Command Format: IBRT -i(input) -b(bright)
