Used by the terminal to inform the ASCII Triggering device that the
operator has pressed the ACK key in response to an alarm message.
Format: [Ctrl-K]Message#[CR]
•
Message# range: 1 to 9999; limited to the subset used in the
application
Example: [Ctrl-K]75[CR]

The terminal displayed message #75, which was defined as an
acknowledgeable message. The operator pressed the ACK key,
and this response message was sent to the ASCII Triggering
device.
Report a function key press with [Ctrl-F]
Used by the terminal to inform the ASCII Triggering device that the
operator has pressed a function key.
Format: [Ctrl-F]Message#\ F-key#\ F-key action[CR]
•
Message# range: 1 to 9999; limited to the subset used in the
application
•
F-key# range: 1 to 16
•
F-key action range: 0 or 1; the application defined the function
key as Normally Open or Normally Closed; this Normal state is
defined as 0.
Example: [Ctrl-F]33\ 5\ 1[CR]
•
When the terminal operator pressed function key #5 which was
enabled in Message #33, the terminal informs the ASCII
Triggering device that the function key has changed to the altered
state.
Note: If the operator presses a momentary function key, the
terminal will automatically send another [Ctrl-F] message when
its Hold Time is up:
[Ctrl-F]33\ 5\ 0[CR]
Note: If a latched function key is unlatched after the terminal
receives a [Ctrl-U] message, the Message# parameter in the
[Ctrl-F] message is 0.
