How does one send simple serial data using built in serial ports from a carbon application? I need to send and receive RS-232c Serial data from my carbonized application, but I understand the Communications toolbox is unsupported under carbon? If this is true, how does one send/receive serial data other than the ridiculous complexity of open transport? I need code example on how to identify the ports, open one and set it's com specs (baud, bits, parity, etc.), send data aynchronously and receive data asynchronously. This used to be fairly simple with Comm Toolbox but what do you do with carbon. Can you make comm toolbox calls from carbon app under MacOS 9.x? I don't need it yet under MacOS X, besides MacOS X provides a new way to serial I/O, I think.
