Re: Acccesing the ISA port
ISA is a bus not a port. You need to know the port(s) the card occupies on the bus in order to talk to it. Although I would suspect the bluetooth cards have a Visual Basic API to talk to them it is very rare to talk directly to a port. Normally there is a Device Driver that sits between your application and your hardware. Also I am not sure that Visual Basic can talk directly to ports. C++ can (_outp and _inp) If you must talk to a port directly you may need to write a C DLL to act as a API for your Visual Basic app.
