Listing serial (COM) ports on Windows?

Using pySerial with Python:

import serial.tools.list_portsports = list(serial.tools.list_ports.comports())for p in ports:    print p

python c windows winapi serial-port

Several options are available:

Call QueryDosDevice with a NULL lpDeviceName to list all DOS devices. Then use CreateFile and GetCommConfig with each device name in turn to figure out whether it's a serial port.
Call SetupDiGetClassDevs with a ClassGuid of GUID_DEVINTERFACE_COMPORT.
WMI is also available to C/C++ programs.

There's some conversation on the win32 newsgroup and a CodeProject, er, project.

python c windows winapi serial-port

The PySerial project provides a couple of solutions.
