PPT should be using COM1. What can I do to fix this?
The way your sytem should be set up is that you have a rendering computer and a PPT computer.
The PPT computer is connected to the rendering computer over a serial crossover cable (Nullmodem cable).
The PPT computer is set (under options) to send data over COM1 (the PPT computer has only one serial port, which is COM1).
The Vizard computer has the serial connection from the PPT computer connecting either to a native serial port (if there is one). For newer computers which do not have a serial port it is connected over a USB to serial dongle (less recommended) or over a PCI - to - serial card (more recommended).
In both cases there is a very good chance that the Port the PPT is connected to is not COM1 on the rendering computer.
exactly the way it is done here (i.e. capital letters) and put the line with this command right in front of the line (viz.add('vizppt.dls') )where PPT is added.
That seems to have worked as the log now notifies me that it has connected to the PPT tracker. I worry that something is still not working correctly though as moving the tracker has no impact on the world. I was under the impression that PPT information was used to control the head position in the Gallery world.
