Serial Port For Mac

You should have a look at ZOC, what I think to be the best terminal emulation program available for the Mac. I use it everyday for my job. It has the ability to do direct communication with a serial port. Of course it does way more than just serial communication. ZOC is a professional SSH/telnet client and terminal emulator. TRENDnet USB to Serial 9-Pin Converter Cable, TU-S9, Connect a RS-232 Serial Device to a USB 2.0 Port, Supports Windows & Mac, Supports USB 1.1, USB 2.0, USB. Serial Tools for OS X, includes a Terminal Emulator, a Protocol Analyzer, and a serial port monitor to watch for connections and removals of serial ports. Serial Tools is completely free, and available from the Mac App Store.

Information about these and other types of Mac ports is in the specifications for your Mac: Choose Apple menu  > About This Mac, click Support, then click Specifications. Or check your Mac user guide.

Thunderbolt 3

Use Thunderbolt 3 with displays and other devices that connect using either a Thunderbolt 3 cable or USB-C cable. You can also connect a USB-C power adaptor and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adaptor to connect it.

These Mac models have Thunderbolt 3 ports:

If your Mac notebook or desktop computer has more than one port like this, each port supports ThunderBolt 3 and USB-C.
