iocore_gpo: <name> | <channel> | on/off | <duration>

Assuming the named node is a Visual Productions’ ioCore2, uses the ioCore API to control the GPO ports on that node.

• name is the name of the node to be controlled
• channel is the number of the GPO to be controlled
• The 3rd field must be either on (closed) or off (open), and sets the state of the GPO
• duration is optional – if present, the GPO will be pulsed in the direction indicated for the duration in milliseconds.
