need com port

my arduino comes up as /dev/tty.usbmodem411 rather then a com port what do i do

Tiger, You are on a MAC, I think. Right??

If so, that's what a "Com" port looks like on a MAC.

Look at: http://arduino.cc/en/Guide/MacOSX#toc3

and "Select Your Serial Port" AKA COM Port ...

ok i am on mac so i am all good now :slight_smile:
