Change serial example to a non-numeric string e.g. N0000002 to document that serial numbers can be non-numeric and avoid the mentioned issues with rtl_ commands interpreting numeric serial numbers as device index
Add a note that rtl_ commands accept serial numbers for the -d parameter as this is not obvious and not documented in manpages
