LSOF 3.61 (which runs now under CURRENT thanks to Vic Abell) displays that:

uulog     17591  roberto    0u  VCHR     5,     4    0t97077       3170 /dev/ttyp4
uulog     17591  roberto    1u  VNON                                    
uulog     17591  roberto    2u  VCHR     5,     4    0t97077       3170 /dev/ttyp4

and

less      17592  roberto    0u                                          unknown file system type: 7
less      17592  roberto    1u  VCHR     5,     4    0t97077       3170 /dev/ttyp4
less      17592  roberto    2u  VCHR     5,     4    0t97077       3170 /dev/ttyp4

Some fiddling inside  LSOF or the kernel   should show the  proper type for
both descriptors.
