Hi, This is the first time I am trying to do Mac programming. I need to communicate with my device through USB/Serial adapter. As far as I understand, I need to write a serialport library for this, but I have no idea where to even begin. Do I really need to learn Carbon or Cocoa to do this? I hear that some of the C libraries are not supported for Mac OS X. I need to get this done asap, so I would really appreicate your inputs! Thanks!
