Hi:

I've been playing with serial ports on my Powerbook G3 and I discovered some not so nice actions in class SerialPort. If the port is in use elsewhere, trying to open it gets a Primitive Error.

I'd rather have my code get back some indication that the port didn't open, so I made some small mods to SerialPort, which are attached. Basically, primitives used during open answer nil if they fail, and the open method answers nil also.
