Script access of ttyUSBx on Zee

[wbmurray]

Hello - I'm attempting to modify a vbscript I've used with my Denon receiver on HS2 with PC successfully for a couple years. Background is here

I've migrated to Zee and need to make this vbscript conform with vb.net.

The first challenge I have is opening the serial port (usb-serial). I have confirmed the Zee is connected to the usb-serial adapter and can talk to the Denon by running Minicom from the console.

Here's what I've researched...which errors.

imports serial
imports system.io.ports

Sub Main(ByVal parm as object)

ser = serial('/dev/ttyUSB1','BaudRate',9600);
ser.write("PW?")
ser.close()
End Sub

The error I received is :
"Error Compiling script /usr/local/HomeSeer/scripts/comnuvo4.vb: Expected ')'.{0xD}"


Any help would be appreciated.
