Check for serial communication protocol

Hi,

I want to check if a serial communication protocol exists on the computer where i want to do the install. I don't have any idea how I can do that. Have somebody an idea?

Thanks,

Since you haven't idea how you can do that, as you mentioned, I'd like to know please, how does this affect your installer.
What you would do with your installer when you check if a serial communication protocol exists?
