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
• Break support
• Text pacing
• XMODEM, YMODEM, ZMODEM and Kermit file transfers
• Manual or automatic logging
• Profiles
• Timestamps
• Emulated break sequence for devices or kernel drivers lacking support
• Emulated XON/XOFF for devices or kernel drivers lacking support

Serial includes built-in support for the following devices:

• USB Communication Device Class (CDC) devices
• Bluetooth Serial Port Profile (SPP) devices
• USB to Serial bridges based on the FTDI, Prolific, CH34x, SiLabs, and TI chipsets
• FTDI's FT260 HID USB/Serial Bridge
• SiLabs CP2110 HID USB/Serial Bridge
• Cisco (and other) devices with built-in USB console ports


Release Notes:

- Added support for clear scrollback escape sequence
- Fixed set cursor position escape sequence
- Other minor fixes and improvements

Review by RosebudYT

Nice job - I’m a Cisco networking administrator. This tool works great with my new MacBook (the one with only 1 USB-C port). I have the Apple brand USB-C to USB adapter. This terminal emulator works immediately with a generic Prolific USB to Serial adapter, which NO LONGER WORK IN EL CAPITAN. Let me stress that, anyone reading this review. The only way to get a USB to Serial adapter to work, other than this excellent utility, is to modify your operating system and remove safeguards to prevent unsigned applications from running. I do not recommend doing that. This terminal emulator works great. No playing around with “screen” or whatever it was I was using before. Plug in your console cable, hit enter twice and you are at the command line. And all the putty functionality that you are familiar with works. No drivers needed for the USB to Serial adapter. Great job, DTI.

no logging support - I am quite disappointed that there is no ability to log a serial session. The only option is to export the text of the session, after it is complete. I have never used a serial emulation app that didn’t have this function (on Mac or Windows), so I didn’t even think to verify this feature was available before purchasing. Logging a session is very important for network equipment admins for a few reasons. First, you may be logging serial output for an extended period of time, and you want to make sure you have as much data as possible (and don’t want to have unlimited scrollback), especially when unexpected events occur. Second, you can monitor the file output to trigger scripts or other processes to help in troubleshooting. Third, you might not want to have the whole session as output. You can do multiple copy-and-pastes, but temporarily logging a portion of the session is a standard way of going about this. Not to mention it is darn convenient and gives you that warm and fuzzy that information is already stashed to a file. To be fair, the rest of the app’s features seem solid. I wish I would have used the free trial, which I encourage everyone else to do. I didn’t see that was available from their web site until after purchasing through the app store. If the app had been $5, I could see letting it go. But I had to shell out $30. Unfortunately, I am going back to ZTerm.

Version 1.3.5
Review by Ted E. Bear

Great app if you use serial consoles at all, one little flaw... - I love this app, works with all serial adapters I’ve tried, great UI, doesn’t leave sessions open that I forget to close, etc One bug I found was that it crashes loginwindow when used in conjuctiion with Remote Desktop and the built-in serial port on an Xserve. And then when I try to force quit Serial, it becomes a zombie process. I send HUP to loginwindow, and it doesn’t come back, so I have to power cycle the Xserve out-of-band. It’s considered vintage so no longer supported, but it runs Yosemite, and it is a bug, though it might not affect many people. So I have to use screen for using the serial port on the Xserve, but other than that, it is a great app, well worth its price. I’d love to be able to use it with the Xserve serial port though.

When you need it, you need it - Apple doesn’t seem to think we need serial port support. So if you have to use a serial console over USB, this is the best app to get.

Version 1.3.5
Review by JustinoCXI

Spectacular - My company stopped using Windows laptops several years ago but, they’d been keeping one old Toshiba for years because they needed it to console a SunOS box in case of an emergency. The HD died on that poor old Toshiba a few months ago and left us in a world of pain because we had to reboot the Sun server a few days later and couldn’t watch to see what was happening. That turned into about 30 minutes of three guys scared and twitching because we didn’t know if the machine was booting or not and it doesn’t have a VGA port to plugin a monitor. So, after that madness, I started looking for a way to get USB to serial access on our MacBooks rather than doing something like putting an old desktop next to that server. I googled here and there for a few days and kept finding forum posts from the guy that wrote Serial. I finally decided to download the trial version and test it out. I plugged in my USB to serial adapter and it just popped and worked without me having to find the drivers or anything for it. That’s amazing! Anyway, I’d recommend this to anyone that needs a Mac alternative to Putty or HyperTerminal.
