SSH Support NEW

Serial is now a full featured SSH client with a comprehensive built-in identity manager and the ability to organize and group your favorite hosts.

Telnet and Raw Socket Support NEW

Serial now includes comprehensive support for Telnet, including the RFC2217 extension for remote serial port control supported by many serial device servers. Serial supports raw TCP sockets as well.

Flawless Emulation

Serial is a full-featured terminal emulator supporting Xterm, VT102, and ANSI terminal controls. This allows you to navigate the menu-driven interfaces found in many routers, firewalls and switches and use text based programs including emacs, vi, and nano as if you were connected over the network.

No Drivers

Serial includes built-in, reliable support for almost every serial device on the market, sparing you the hassle of finding, installing, and updating drivers.


Had several USB-serial adapters which no longer had drivers for Catalina. Serial claimed to support pretty much anything and, skeptical, I tried it despite the price. It is absolutely true: you run it, if finds and recognises the arcane adapters your are using and it connects. No kext, no nothing. It just works. Would have never believed it if I had not seen it in action. Worth the money!  — w1nt3rs3a

 The best serial terminal app, hands down
I use this application in my electronics hobby, for talking to the consoles of Raspberry Pis, Arduinos, and whatnot. This is hands-down the best application of it's kind that I've encountered. Not having the hassle (and potential security risk) of dealing with random 3rd-party driver KEXTs is the real killer feature of this app. The rest of it being easy to use, feature rich, and trouble-free is icing on the cake!  — thorpejsf

 Best Serial APP
This is hands down the best serial applicaton I have used for the MAC. I am constantly needing Serial access to various Cisco and HP switches/routers etc. This app has not failed me once. If I had any complaint it would be that the serial port for my Cisco 3560x over USB shows garabage for the name. But when selecting it it works perfect. I wish I could attach a screen shot here which would explain this better.  — Kris.Armstrong
