Connect to serial port using PuTTY


I want to connect with my serial Port using the PuTTY program, but it's not possible: When I click “open” nothing happens, I only hear a “Beep, Beep …” under a Windows 7 or MAC OS X with VirtualBox.

The following screenshot shows my configuration for the serial port and the settings in PuTTY.

Solution

  • The first thing I'd do is make sure you can connect to your external device using the Host OS directly. Since you're on a Mac you can use screen from the command line (since you're using 9600 baud):

    screen /dev/ttyS0 9600
    

    If that doesn't work then you're dead in the water.

    Then make sure your host's serial port is exposed to your Virtual client. From your host Virtualbox settings you'll need to pass through your serial port (like here https://superuser.com/questions/436049/how-to-use-host-serial-port-from-guest-in-virtualbox).

    In Putty then you should be able to connect to the COM port you passed through.
