I have a USB to serial converter. I don't know the manufacturer but found something on the internet that looked like it so I downloaded their driver. Now (I'm new to a Mac) I need to see if it works. 1) Is there a way to display all of the devices in a GUI such that I can identify the com port? (I did "ls /dev" and I see ttys0, etc (about 20 or so)) 2) I need to know which tty the converter belongs to. How do I do that? 3) Once I identify it, how do I set the serial parameters?
