    Re: Question 2

    Yes, there are wireless Ethernet shields. Click to see one.

    When using multiple shields, make sure there aren't any pin conflicts. I2C and other interfaces usually have unique addresses. Also, depending on which Arduino you are using, check that it supports the shields you are considering. Some require modifications to work. For example, there are specific mods on a MP3 shield and a Mega.

    Adafruit sells several Wifi shields for the Arduino.

    So does that mean it depends on if they are stackable?

    How would you know if there is a conflict? Will the list the peripherals it uses?

    What about binary in / out lines? Assuming the Arduino has such an animal.

    My other question is, will the ethernet connection act like a com port to the PC much like the USB port does?

    Re: Question 1

    It is likely stackable. Make sure that all intervening shields have stackable headers. Since most shields package the headers separately, for you to solder, you can always buy stackable headers if your shield doesn't come with them.

    This site maintains information for most of the Arduino shields, and allows you to check for pin conflicts. Find your distributor/manufacturer, find the board you want, and check the drawing on the pins it uses.

    No one yet answered by question if ehternet connection on Arduino acts a a terminal (serial port). Anyone know?

    That is the internal connection between the Arduino and the shield. Ethernet communications are handled through the associated library. The functions provided in the library may act like a terminal. I am inspecific because your description of the communication as a terminal is vague to me.

    The library for that shield is documented here. When researching an Arduino shield, I make sure I understand the library first. Each product description usually contains a link to the library documentation.

    What I need to know is can I see it as a comport on my pc so I can connect instead of using the USB connection. I want it to be wireless from my PC.

    I'm no comms expert, but I believe the answer is "no." It would be a TCP/IP connection, not a COM port or equivalent.

    If what you want is effectively a "wireless COM port" then you might consider a couple of XBee modules to create a serial link, or possibly Bluetooth LE.
