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

在 MATLAB Online 中打开

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.
