Hej!
I still wonder if anyone has gotten a parse refclock running under NetBSD
(if that matters on this subject, -i386).
I still cannot get the xntpd to configure the clock, because it wishes to
use async I/O and therefore tries to set the tty owner.
I get:
Sep 3 17:58:41 zippo xntpd[7341]: xntpd 5.85 Tue Sep 3 17:50:44 MET DST 1996 (1)
Sep 3 17:58:41 zippo xntpd[7341]: tickadj = 40, tick = 10000, tvu_maxslew = 3960
Sep 3 17:58:41 zippo xntpd[7341]: fcntl(F_SETOWN) fails for clock I/O: Inappropriate ioctl for device
Sep 3 17:58:41 zippo xntpd[7341]: PARSE receiver #1: parse_start: addclock /dev/refclock-1 fails (ABORT - clock type requires async io)
zippo# ls -l /dev/refclock-1

zippo# ls -l /dev/tty01

zippo# dmesg | grep com

com3 at ast1 slave 1: ns16550a, working fifo
com4 at ast1 slave 2: ns16550a, working fifo
com5 at ast1 slave 3: ns16550a, working fifo
com0 at isa0 port 0x3f8-0x3ff irq 4: ns16550a, working fifo
com1 at isa0 port 0x2f8-0x2ff irq 3: ns16550a, working fifo
So, basically, what do I have to do to use async I/O with -current?
