man plp(4) states that the magor device number for
IOP based printers in 48, /etc/makedev uses 43.
Does anyone know which is right?
The reason I ask is becuase we are tring to get an IOP based
printer to work. We used /etc/makedev to create /dev/iop/plp0,
and everything lpd sends to the printer fanishes. And so
far this is the only thing I can find 'wrong'.... but I can't
find much info about IOP printers....

The deciding factor of the device major number is the [bc]devsw tables in /usr/sys/conf/conf.c. My system version has it set to 48 also.

On an OSx4.4 system ... [sugar] ls -l /dev/iop/plp0 c-w--w---- 1 lp 48, 0 May 4 1988 /dev/iop/plp0 while on OSx5.0 ... [pyrps5] ls -l /dev/iop/plp0 c-w--w---- 1 lp 43, 0 Jan 11 11:55 /dev/iop/plp0 And as cal@pyrtech (Craig Alan Levin) noted in <98007@pyramid.pyramid.com>, the major number can be verified by looking at the cdevsw[] table in /usr/sys/conf/conf.c, which on OSx5.0 contains the entry /* 43 */ { /* IOP printer */ glpopen, glpclose, nodev, glpwrite, nodev, nodev, nodev, 0, seltrue, nodev, SLAVEOK, 0, sio_nodev, }, So your /etc/makedev is correct and it looks like the man page for plp(4) didn't get updated in the 5.0 release. I'll pass this on to the appropriate people. Thanks for pointing it out. Mike. moliver@pyramid.com {allegra,decwrl,hplabs,munnari,sun,utai,uunet}!pyramid!moliver
