Machine Interface Format (MIF)
Understanding command-line basics
MAX Administration Guide
C-7
The <value> established in the SET command sets the time period in seconds between status
checks. For example,
: SET 100.ALARM.0.alarm=20
- 100.ALARM.0.alarm=LA
:
Reports are generated only whenever a change is detected in the requested status window
components or whenever an alarm occurs. If the <value> in the SET command is 0,
asynchronous reports are not generated.
Understanding command-line basics
Begin using the MIF command line when you understand Command Line Length, Command
Echo, Line Terminations, Prompt, and Output Indicators.
Table C-2 summarizes command-line processing in MIF.
Table C-2. Command-line processing
Command Line Length
The maximum command line is limited to 76 characters.
Data entered after the 76th character is ignored and not
echoed to the screen. The line is not terminated until a
Line Termination is entered.
Command Echo
All data entered by the user except the line termination
character will be echoed back to the user, character by
character.
Line Terminations
Lines are terminated by either a Return (
ASCII
<CR>
), or a Line Feed (
ASCII <LF>
), or both. When
either is first received, the sequence
<CR>-<LF>
is
echoed. An
<LF>
following a
<CR>
does not result in
an additional
<CR>-<LF>
being echoed. The Line Ter-
mination character may be entered at any point on the
line; the entire line is accepted.
Prompt
The display of a prompt is an explicit acknowledgment
that the previous entry has been processed and that the
system is now ready to process the next request.The
default prompt is a colon (
:
).
