Here is a sample of what I get with a KeySpan USB-serial adapter connected:
KeySerial1,/dev/tty.KeySerial1,/dev/cu.KeySerial1 USA28X1a2P1.1,/dev/tty.USA28X1a2P1.1,/dev/cu.USA28X1a2P1.1 USA28X1a2P2.2,/dev/tty.USA28X1a2P2.2,/dev/cu.USA28X1a2P2.2 Bluetooth-PDA-Sync,/dev/tty.Bluetooth-PDA-Sync,/dev/cu.Bluetooth-PDA-Sync The one you need to use to connect is the 3rd item i.e. the one starting with /dev/cu. instead of /dev/tty. While LiveCode cannot communicate directly with a USB port, it appears that the Arduino is providing a serial port, so this should work fine. On my web site, there is a serial test stack <http://www.troz.net/rev/stacks/SerialTest.rev> that might help you diagnose the connection issues.
