Brains Development / Can brains read the status of a device of a PC ?

Can brains read the status of a device of the PC on with is running Mach3?
I'd like to know if is possible that in a brain I can define a variable that read the status of a COM (or  serial) port. It does already exist?
Thanks for your attention
