CUE & SCENE CONTROL THROUGH THE MONITOR PORT
(Firmware versions 3220116P and following.)

CUE PLAY, STOP, AND RESET

The command PQ followed by a number will start a cue, provided it has
been successfully downloaded.  The number is expressed in decimal 0 to
511.  Leading zeros are permitted but not necessary.  Spaces after the
PQ and before the number are also permitted.  The PQ may be lower case.

If the cue does not exist, there is no effect; if the cue is already
playing there is no effect.  In neither case is any indication returned
on the display.

The command SQ followed by a number will stop a cue.  All the provisos
from above for PQ apply here also.

When a cue is stopped, it is merely suspended and its state does not
otherwise change.  If PQ is used to start the cue (or a command from
another running cue, or a cue-control becoming active), the cue resumes
where it left off.  If it was in a delay or a wait, this continues after
the cue is restarted.

The command RQ followed by a number will reset a cue.  All the provisos
from above for PQ apply here also.

When a cue is reset, it is stopped AND any delay or wait in progress is
cancelled, and the cue event pointer is set to the first event in the
cue.  Thus, when the cue is started again, it plays from the top.

ANIMATION PLAY, STOP, AND RESET

A format, exactly parallel to the commands (above) for playing,
stopping, and resetting cues, is provided for control of ‘animation
scenes’.  The format is, for example, PA8, SA17, RA12.

INTERNAL ICM STATE AFFECTS ABILITY TO SEND COMMANDS

Note that these commands are executed only if certain conditions within
the ICM are met.  Among these are that the menu system must be
presenting the show screen, if a handheld is attached.  Also, within a
few seconds of an ordinary protocol message, the port will ignore any
non-protocol presentations.

If an external device is used to transmit these commands (as opposed to
typing them from the handheld keypad), the port will be in the correct
state after ICM startup is complete.  However, the communicating device
should NEVER send an ESC character, and should NOT echo any characters
that are sent from the ICM’s monitor port.

The communicating device must be able to tolerate the ICM’s poll for the
handheld, which is an 0x05 character sent about once per second.
