Matlab Serial Communication on MAC

So Im trying to open a com port on mac osx

According to a tutorial from math works I'm suppose to use the following

Mac OS X 64 serial('/dev/tty.KeySerial1');

What is KeySerial1?

I tried going to mac system info but and looking under the USB section but don't know what name to use to open the correct port. Any ideas?

Thanks

There is no real standard for the name that will be associated with a USB based serial device. Typically, though, the device name will match /dev/tty.* including the period literally. So in MATLAB, try

!ls /dev/tty.*

and see if you find anything.

The default Mac serial ports have names that match /dev/tty[p-w][0-9a-f] . Also, you will probably see /dev/tty.Bluetooth-Incoming-Port which will not have anything to do with USB.
