Empty map returned by built-in serial ports is confusing #60

Open fhunleth opened 5 years ago

fhunleth commented 5 years ago

Setup

Expected Behavior

When enumerating serial ports on Linux, the built-in ones should return some information - even if it is just that they're built-in.

Actual Behavior

The built-in serial ports return empty maps.

Steps to Reproduce the Problem

Enumerate serial ports on a Raspberry Pi, BBB, or any platform with built-in serial ports.
