PS> $port= new-Object System.IO.Ports.SerialPort COM3,9600,None,8,one
PS> $port.open()

Reading from a Serial Port

PS> $port= new-Object System.IO.Ports.SerialPort COM3,9600,None,8,one
PS> $port.Open()
PS> $port.ReadLine()

For information about how to read from a serial port in an asynchronous manner in PowerShell V2, use the DataReceived event on the port object with the Register-ObjectEvent cmdlet.

Enjoy!
