concerning animations, why is it that whenever a specific duration in
seconds, the animation always seems to be longer than the specified
duration? it just doesn't seem precise. i recall to have the same
issue with something else other than animations. anyone else notice
this?

What do you mean by "seems to be"? Human beings have a very subjective

If you want to access the serial port via Objective-C classes try
AMSerialPort. It is a collection of classes to access serial ports. I
have used it extensively for my serial programs and it works very well.

Not sure what you mean by Cocoa Animation.

Sorry,
Thanks for asking.
On the write, errno = 2 and strerrno(errno) returns "No such device or file".
On the read, errno = 35 and strerrno(errno) returns "Resource temporarily

Clearly the write is the issue, but the errno isn't making sense to me.

I have to re-cant this. Write() doesn't set errno, errno is 2 before write() is
called, so the "No such file or device" is not relevant.
Since write() returns the correct value, I'll persue Marco's suggestion to look
at the canonical vrs non-canonical issue.

So essentially you want to mimic IB? Register your window
creation/deletion methods with an NSUndoManager that lives in your app
delegate (or elsewhere in the responder chain). Then your "deletion"
is really just hiding the window from view. If the user undoes the
deletion, the window is shown a
