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. With Serial there is no need to change security settings on your Mac just to connect something to your machine.

For network administrators, Serial supports the break sequence required when working with routers and switches, and even emulates breaks for devices and/or drivers lacking direct support. In addition to breaks, text pacing allows you to paste large configuration files without overflowing the input buffer of your device.


• Full-featured xterm, linux, and ANSI/VT100 terminal emulation

I have been looking for a replacement for Z-Term for years. I did the free trial and I was amazed on how easy this was to use. Within 30 minutes I went ahead and purchased the product. Very well built and works well.

Amazing! Please Consider An iPad App!

Such a pleasure to use. An app like this is one of the few things missing from my iPad. Please consider making an iPad version.

Most stable and usable

I’ve used this app for last 3 years. It’s the best serial terminal emulator by far including those on Windows.
