HP-UX 10.20 devices

Is it possible to create the CDROM device file for a drive attached to the parallel port? I have a removable CDROM drive (gift - I'm trying not to return it, but may have to anyways) that attaches via parallel port. The only device that I can attach to that hardware address is /dev/c1t0d0_lp, a printer device. I may be going about this all wrong, since I'm very new with HP-UX / hp9000's, but I can't seem to get the major/minor/driver/etc. correct...

Also, I think I already know the answer to this, but is it possible to create /dev/zero and /dev/(u)random on an HP-UX system? I didn't see anything in Sam's kernel config, so I doubt it, but it's worth a try, I suppose...
