- The best way would probably be to get one of the serial port objects.
- To read the data from the port you basically send a readData: message
- to the object and pass it a buffer...
-
- BenaTong has an object called SerialSolutions. I think it's $50, and
- it looks easy to use (I have only seen the API - I have not used it).
- It's probably worth checking it out.
