CoolTerm – Great Windows / OS X USB-Serial Console App

I typically have used iTerm and the screen command for USB-Serial console access.  But CTRL-Break is a nightmare.  SecureCRT is a great app, but they are up to $99 w/only 1-year of upgrades.

CoolTerm is a fantastic little free Windows and OSX Console program.  With a little tweaking it is perfect for serial console into routers/switches.

Once loaded, make the following changes in Options:

  • Select your USB-Serial adapter on the Port list.  Re-Scan serial ports if you didn’t plug it in before launching.
  • On the Terminal menu option select “CR” for Key Emulation, and Check the “Handle Backspace Character.”

Good to go.  Control-Break is just Command-B on the Mac.  Can’t beat that.

  1. My favorite is using the built-in term of my mac. After plugging in your USB serial adapter and loading it’s drivers, open term, cd /dev, do a ls -l tty*.* and find your adapter. Then screen /dev/tty(your adapter) and voila.
