How to find the serial port number on Mac OS X?

Question

I have just started experimenting with Serproxy and Arduino to get some serial data into Flash Builder/Flex. Serproxy seems to work fine and seems to connect to whatever port is specified. However, I am not able to see or read any data from the serial port using ActionScript. This is odd, because the Arduino should be printing data on a loop.

The only thing I can think of is that I am not setting the correct serial port number. I have been trying to figure out how to find out what number should be set, that is, 5331, 5332, 5333, etc.

How do I find out the port number? Is there a way to do this using Terminal on OS X maybe?

Answer 1

You can find your Arduino via Terminal with

 ls /dev/tty.* 

then you can read that serial port using the screen command, like this

screen /dev/tty.[yourSerialPortName] [yourBaudRate] 

for example:

screen /dev/tty.usbserial-A6004byf 9600
