EPI MSGID—Prefix Message IDs

The MSGID command determines whether output lines that all EPI host commands return to the EPI external data queue have a prefix. This prefix, which begins with the characters OPS, consists of an eight-character message ID and a trailing blank.

This command has the following format:

ADDRESS EPI "MSGID keyword"
  {ON|OFF}

ON

Causes message IDs to be prefixed to output lines in the external data queue. ON is the default setting.

OFF

Causes output lines to return to the external data queue without prefixes.

Default: ON

Example: EPI MSGID

The following turns message prefixing off:

MSGID OFF
