Ready for macOS Sierra

Did a recent upgrade leave your device behind? Serial will get it working again while leaving your Mac's security features intact.

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 via SSH or Telnet.

Less Guesswork

Take the guesswork out of working with serial ports. Serial recognizes your connected devices and lists them by name and type so you don't have to decipher their cryptic BSD /dev paths. Better yet, Serial lets you rename your devices in a way that makes sense to you.

For System Administrators

There’s no easier way to connect your Mac directly to routers, firewalls, PBX systems, servers and more. Serial supports breaks required to access special features within Cisco and other network devices, and allows for firmware and configuration uploads.
