Is there a device out there that will allow me wireless communications to a serial port and or LAN port with my laptop computer? The devices I had in mind are Scadapacks.

If so how many dollars would we be looking at?

Your 2 cents will be appreciated!!!

 

There are many, here is one:

You will need a lot of "2 cent" donors to pay for any of them.
