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:

- Fixed potential crash at launch during log rotation

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.

Review by Tikidiction

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.

Yeah, this app is great. - Good work, developers. You’ve managed to write some software that DOESN’T make other developers complain. This is good stuff. Worth the $30 even if it’s just a few megabytes of code.

Version 1.3.7
Review by AaronF LA

Worth It - I’m an old school guy that has been using GNU screen in Mac OS X terminal for years for serial connections. I finally decided to spend the money on this app, and I’m glad that I did. The fact that the drivers are included is a huge time saver and this app is much easier to work with then GNU screen. If you need serial connections on a regular basis, do yourself and favor and get this.
