I want to write and read data in a Panel View 550 from a FlexLogix (1794L33) controller. I know it can be done by sending a message in a ControlNet or Ethernet environment. But I want to do it through the serial port (via an AIC, maybe). Has anybody done it before? I think it could be done by means of another MSG, but I dont know how to specify the serial port as the route for the message.
