More FreeBSD 6.1: open(/dev/lpt0, O_WRONLY) hangs up
More information about my /dev/lpt0 problem:
1. Enabling or disabling ACPI has no effect.
2. If I boot up in single user mode, I can cat a file to /dev/lpt0
and it prints on the printer.
3. Once I go to mutliuser mode, open("/dev/lpt0",O_WRONLY) hangs
forever whether I start lpd or not.
4. If I "shutdown now" to get back to single user mode and then
"cat datafile >/dev/lpt0", it hangs until I type control-C, at which
point the shell says: "cannot create /dev/lpt0: Interrupted system call"
(which really means, looking at the code in /usr/src/bin/sh/redir.c,
"cannot OPEN /dev/lpt0").

FreeBSD 6.1: open(/dev/lpt0, O_WRONLY) hangs up
Print jobs get into my print queu, but they don't get out. So I started debugging lpd. After a lot of screwing around, I discovered that the program was hanging up on line 1875 of printjob.c: pfd = open(pp->lp, pp->rw ? O_RDWR : O_WRONLY); pp->lp is "/dev/lpt0" pp->rw is 0 So then I returned to my shell prompt and typed in: cat /dev/null >/dev/lpt0 and that hung up uninterruptibly. What's going on? FreeBSD 6.1-RELEASE, unmodified generic kernel. All this worked normally under 5.3, though that needed 'hw.intr_storm_threshold="2000"'. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
