  • 115200/8N1
  • Baud: 115200
  • Data Bits: 8
  • Parity Bit: No

Find the COM# from Device Manager > Ports (COM & LPT) and look for USB Serial Device (COM#). Example: COM3
Alternatively, run the following powershell command to list ports:
Open PuTTY and select Serial. Enter COM# for serial line and 115200 for Speed. Click Open.

Find the Key Croc device from the terminal
ls /dev/tty*" or "dmesg | grep tty
Usually on a Linux host, the Key Croc will register as either /dev/ttyUSB0 or /dev/ttyACM0. On an OSX/macOS host, the Key Croc may register as /dev/tty.usbmodemch000001.
Next, connect to the serial device using screen, minicom or your terminal emulator of choice.
If the screen application is not installed it can usually be found from your distribution package manager.
sudo apt install screen
Connecting with screen
sudo screen /dev/ttyACM0 115200
Disconnect with keyboard combo: CTRL+a followed by CTRL+\

MacOS users may follow the same recommendations for connecting to the Key Croc serial console as Linux users.
Many MacOS specific applications exist for connecting to and managing serial connections however, with Serial 2 by Decisive Tactics being a favorite. See
