When a Serial Resource (e.g. COM1) is busy with another application, I want to tell the operator this, specifying the COM number in question. It appears the Port Binding (e.g. COM1) is not known until a successful VISA open has exececuted. Although I could indicate the alias (e.g. ASRL1::INSTR) that is busy, its not very meaningful. Visaconf.ini has this information. Is it the right place to go for it?
