Serial Terminal For Mac Os X

Kitty Terminal can be easily considered among the best PuTTY alternatives for Mac OS as it’s a robust, multi-platform, and a GPU-supported terminal emulator. The program transfers description to the GPU and makes the OpenGL to work for quick, multi-platform performance. Serial Tools is a set of serial port tools for Mac OS X. It includes a Terminal Emulator, a Protocol Analyzer and a serial port monitor to watch for connections and removals of serial ports. Serial Tools is built as a Universal Binary application and works natively with both the PowerPC and the Intel based Macintosh running Tiger (Mac OS X 10.4.

  • Serial makes it easy to connect your Mac to almost anything with a serial port, including routers, switches, PBXs, embedded devices and more. In addition to a full-featured terminal emulator, Serial includes built-in, user-space drivers for many popular devices, saving you the hassle of finding, installing, and updating drivers.

Using screen as a serial terminal on Mac OS X

Geek Inc.

If you develop on an Apple and find yourself doing any sort of device or embedded development, you will quickly find the need for a serial terminal on Mac. There are a few software apps out there, but I find it much simpler to simply use the terminal application “screen”.
This works well particularly if you have an RS-232 serial to USB converter.
The first thing to do is determine which device you want to connect to.

Once you’ve determined which device you would like to use, you can execute the SCREEN command to start the serial terminal session on your Mac. Remember to specify the speed (baud rate) after the device name.

Once you’ve connected, you can use the terminal as you normally would.
To exit (and close the screen gracefully) press:

Screen will then prompt you to quit and kill all of your windows. Press “y” and you’ll be back to your shell terminal.
This method works equally well if you want to connect to a serial bluetooth device. You must simply make sure that the bluetooth device is paired and active. Then you will be able to see the device in the list of devices. Once you’ve connected to the serial bluetooth device with screen, the connection will be held active for the length of your session.
I’ve used this method to connect to the sparkfun Bluetooth Mate Gold. It simply appears as a serial stream that you can communicate with exactly as you would with any other serial device.

I bought a USB Serial port that had MAC drivers. Check before you buy it that it has drivers. Not all USB Serial have MAC support. I assume that you have installed the correct drivers from here.

First, open Terminal (Applications/Utilities/Terminal). Next, type

ls /dev/tty.*

to get a list of your serial lines. Pick the one that you want to open. For example, my list looks like this:

gf:dev gf$ ls -al tty.*
crw-rw-rw- 1 root wheel 18, 4 Jan 25 07:32 tty.Bluetooth-Modem
crw-rw-rw- 1 root wheel 18, 8 Jan 25 07:32 tty.Bluetooth-PDA-Sync
crw-rw-rw- 1 root wheel 18, 10 Jan 25 09:20 tty.PL2303-0000103D
crw-rw-rw- 1 root wheel 18, 0 Jan 25 07:32 tty.SerialPort-1
gf:dev gf$

And I know /dev/tty.PL2303-0000103D is the USB-to-serial adaptor becuase it’s connected, if you unplug it the tty.PL2303-0000103D stops being listed.

Knowing the serial port, you can just type screen portname datarate to show the serial data on the screen. In my case, it was:

screen /dev/tty.PL2303-0000103D 9600

To quit the screen app, type control-A, then control-.


I don’t think that this is very complete, but it worked for me and might help you to get your USB serial working. Please let me know if there anything I can add to complete this piece.
