Com ports on a Mac mini M1

I am running a Mac mini M1 13.5.2 (22G91). I am trying to set up a GMRS Wouxun KG-UV9G 

hand held radio using Chirp programing software with a RTSystems cable. 


I need to find if the computer is seeing the radio in the com port. Where can I find this information 

and Download the software drivers if I need them? Thank you.

Mac mini, macOS 10.15

I have used FTDI based USB to serial devices, and they do not require drivers on recent Macs like yours. In other words plug them in, and they should just work. I recommend that you do not attempt to install drivers since not only should they be unnecessary, they will almost certainly be difficult to install (and prove just as difficult to uninstall).


Macs don't use "com ports" but their Unix-like operating system will automatically add the FTDI device to one of its many devices in /dev which you can peruse to confirm it appears:


ls /dev


For example, connecting an Arduino board to the Mac automatically adds the device named tty.usbmodem14101 and connecting an FTDI device adds a device named **.serial


Those are both serial devices, and those names are merely examples.


I don't know anything about RTSystems cables, but if they use the FTDI chipset they ought to be the same.

FWIW, I have used FTDI USB-to-Serial converters myself with success. Unless you are using special direct access features of the device, no drivers are needed


Generic USB-To-Serial converters are based on the Prolific chipset which can be problematic depending on the chips firmware that it has on it. Some of them you can flash newer firmware some of them you can't. I have had a couple over the years and they always end up being problems.


So. personally, I would suggest getting an FTDI converter using this link:

FDTI

I just checked and the ones I have are still recognized and mounted though I don't have anything at the moment to verify if they communicate.
