crw-rw-rw-  1 root  wheel   17,   4 26 Feb 20:01 /dev/tty.Bluetooth-PDA-Sync
crw-rw-rw-  1 root  wheel   17,   0 26 Feb 20:01 /dev/tty.usbserial-00001124
crw-rw-rw-  1 root  wheel   17,   2 26 Feb 20:01 /dev/tty.usbserial-A10048Md

In this case there are two serial devices listed:

  • /dev/tty.usbserial-00001124
