Telnet and Raw Socket Support NEW

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.


 Amazing Tool
I frequently access Cisco equipment, and I used to use ZTerm all the time. But, since it no longer works on modern version of MacOS, I had to find something different. Glad I stumbled across this gem - it's much simpler to use than ZTerm, and I haven't had a single issue. Thanks!  — Pale0phyte

 Super useful
The best serial port tool I’ve used.  — keith_duncan

 NetEng/CLI Junkie's Dream!
If you work on networking gear you WILL LOVE THIS! It buffers what you are pasting, so that you can paste huge amounts of text, and it will paste one line at a time, and wait for the terminal to respond before entering in the next line! No more having to paste 5-10 lines at a time so that the switch/firewall/routers buffers don’t overload! Love it!!!  — Fthvcg
