I don't see how examining the ProDOS 8 block device list helps at all...
there can be a printer card in the same slot that P8 is using for a
"remapped" block device.

The GS Firmware Reference must be talking about the built-in serial
ports, which are indeed slots 1 and 2, when they are chosen in the
Control Panel.  But the user could easily have a printer card in any
slot.

So it seems you should examine $00/Cnxx to see which slots have the
right ID bytes to follow the BASIC or Pascal character I/O conventions.
There is information in the Firmware Reference and the Technical Notes
(especially Apple II Miscellaneous #8, for the Pascal ID bytes).
