Thanks to Jim, my aux ports are working now!
 
The PP must be uppercase, as in the examples below:
rpt cmd 2211 cop 61,PP4=1 0                   ; Parallel Port 4 high
rpt cmd 2211 cop 61,PP4=0 0                   ; Parallel Port 4 low
rpt cmd 2211 cop 61,PP5=1 0                   ; Parallel Port 5 high
rpt cmd 2211 cop 61,PP5=0 0                   ; Parallel Port 5 low
 
73,
