Ever since rev 1.27 of puc.c, the port number that was exposed by puc(4)

Browse Source 
and used by uart(4) for the channel conflicted with the port offset for
the Z8530. The Z8530 has the channels reversed (i.e. channel B is at
offset 0 and channel A is at offset 4). Assign the port offsets in the
right order so that uart(4) will properly attach to the channels.
