Serial Ports Available for PuTTY on Windows

The popular PuTTY terminal emulator has built-in support for serial port console sessions. Unfortunately PuTTY doesn’t seem to provide a way to list currently available serial ports within the GUI. A feature like this would be extremely useful with USB to serial adapters since they seem to be assigned different COM port numbers within Windows depending on the adapter chipset and specific PC USB port used.

Try the following PowerShell command to view the currently available serial ports on a Windows PC:

  • [IO.Ports.SerialPort]::GetPortNames()

You can also view available serial ports within the Device Manager GUI. A quick shortcut to open Device Manager is the command mmc devmgmt.msc then expand the “Ports (COM & LPT)” node.
