dataPortConnectionManager manages the creation and status of Maya commandPorts. A commandPort is a TCP/IP port that listens for data to be sent to it over a network. This tool has been used to open ports in Maya to send it data from Processing, Max//MSP/Jitter, and custom hardware. It's the first step for opening Maya up for interactive application in association with "sensing" devices, like cameras, etc.
for an example of computer vision in Processing talking live to Maya.
1) Source the script
2) Run "dataPortConnectionManager"
3) Input the computer name (optional), port (not optional), and Maya command prepend (not optional).
Test the setup by telnet: telnet localhost 10022 from a command prompt
Now when you send a command over telnet (for example) the string sent will be prepended with the command you specified which can parse the string and do something with the data coming in. The example command is called "dataPortPrintInput" and it just prints the data that it is receiving over the port.
