First of all, if you are running Macosx as you said you were on the brltty list, you need a driver for the serial-usb cable. Second, the ports on the Mac are not named the same as in linux. Usually it would be /dev/cu. with something after the period; for my prolific cable it's /dev/cu.usbserial but for my keyspan I've had different designations like /dev/cu.USa19H1d1P1.1 Once you have he driver installed an dhave the cable and device plugged in, you can run ls /dev/cu.* and see what your choices are. If you are not running Macosx but have put some other unix system on your Mac, see the documentation for that system. -- Cheryl "Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer."
