Command for opening serial port in Windows 7

Question

Is there a Windows command for opening serial ports, say COM3 via the command prompt in Windows 7? For example:

OPEN "COM6" AS #1

I cannot use pyserial or any other utilities that are not distributed with Windows 7.

Maybe you can use the Powershell? It's included in Win7...
