Develop a Plug and Play Hardware

[Dennis_Knutson]

So I searched for other posts you made and found this where you asked a similar question. Are you now saying you don't have a program for this external card? Are you now saying you do not use the serial functions to communicate to this external device?

You can choose to answer or not. I'm going to refrain from this thread. It's just too frustrating, sorry.

you can treat the current post as my this post. So how could i detect that at which port my mobile phone is connected.

Thanks
