How to find the COM port number on macbook

Hi,

I am using a usb to serial(rs232) converter so to connect to a small controller.

Due to programming reasons I need to find the com port number so to be able to connect to the device. Once I connect the converter on windows I just go to devices and printers and find the com number there.

But I cannot find it on my macbookpro runnning mountain lion 10.8.4.

Can someone please help?

Apple Menu (top-left_ - About this Mac etc. Not in front of my Mac at the moment but all the hardware info, com ports, interrupts etc are all there

Hi mrplow

thanks for your reply.

Yes I found the usb to serial converter but not recognizing the COM port number.

On windows I find Prolific USB-to-Serial Comm Port (COM4) for example. but on the mac cannot find it. I found a location ID but there is not written the Comm port number as in windows. Do I need to include this location ID number instead of the Comm Port in the Matlab code to be able to connect?

Did the device come with any drivers/software?

Yes it has a driver software for both mac and windows.

Hi,

Are there any suggestions for my problem pls.

Thanks in advance for your help

I've looked all over but it really depends on the adapter. What make and model is it?

Hi mrplow sorry for the delayed reply but I was not at home.

It is similar to this model in fact from the same website
USB to Serial Converter (CDLSB-901) product ranges from NEWLink

Thanks again for your help

Have a look here. Some useful info. But, I'm afraid, no comm port numbers. OSX and Unix just don't enumerate serial ports like that from what I can understand.

There is info on that page that gives you the device name. You may be able to use that in your code

Ill try it. Will contact you back later this week becuase I think that this link if helpful.

Thanks again.

Hi mrplow,

Sorry for replying this late but I was a bit busy with other stuff.

The link you posted helped me a lot in fact OS X does not have COM port numbers I used "/dev/tty.usbserial" in my code in MATLAB and worked fine.

Thanks for your help

Were you able to establish a connection with the board on your Mac? Can you please help me figure out how to refine the function code in MATLAB if you were successful?

Thanks!
