Hello there Apple... I have a question.
I am running A/UX 2.0 and am using lpq as my printer daemon. This is set
up for AppleTalk on the printer port. My modem port is used as, of course,
a modem port. So of course, everyone should have rw permissions on
/dev/modem and /dev/tty0. What SHOULD the perms be on /dev/printer and
/dev/tty1? What I have (and what 2.0 is shipped as) is as follows:
crw-rw-rw- 1 bin bin 0, 0 Apr 10 04:00 /dev/modem
crw-rw-rw- 1 bin bin 0, 1 Apr 10 04:00 /dev/printer
crw-rw-rw- 1 root root 0, 0 Aug 20 14:12 /dev/tty0
crw-rw-rw- 1 root root 0, 1 Apr 10 04:02 /dev/tty1
Now, since AppleTalk is being used as the printer interface, does this mean
that Everyone must have rw access to the printer port too? I can understand
w access, but r access too? Is AppleTalk 2-way when printing to a LaserWriter?
If so, then I guess rw IS needed, but I would like to know for sure.
Thanks!
