Mac’s and serial TTY’s (Using usb to serial adapter with MAC)

Screen

It’s not actually necessary to download an install extra software, as you can use the Mac OS X built in Terminal and screen. Screen lacks some features, but it does include VT100/ANSI terminal emulation, and can be extremely useful.

1. Open an OS X terminal session (window)
2. Find the right TTY device. Type: ls /dev/cu.*

With the USB-Serial adapter plugged in, you’ll get a list, including something like this:

$ ls /dev/cu.*
/dev/cu.Bluetooth-Modem		/dev/cu.iPhone-WirelessiAP
/dev/cu.Bluetooth-PDA-Sync	/dev/cu.usbserial

1. Then type: screen /dev/cu.usbserial 9600 (in this example).

The 9600 at the end is the baud rate. You can use any standard rate,

eg, 9600, or 19200 for a Sig Server!
1. To quit the screen app, type CTRL-A, then CTRL-.

Type man screen in Terminal for further information on screen. (use ‘enter’ or ‘space’ to scroll, and ‘q’ to quit).
