Hi all, the daemon opens /dev/ttyU3 on startup to read serial data. In case of reboot the device seems to be not ready and the daemon does not get any data even it seems the opn succeeds. It works after manual restarting the daemon. I could not find a suitable rcorder requirement. How could I make sure the daemon does not start too early? Thanks, Axel PS: crw------- 1 root wheel 0xd3 Sep 29 12:54 ttyU3 crw------- 1 root wheel 0xd4 Sep 29 11:56 ttyU3.init crw------- 1 root wheel 0xd5 Sep 29 11:56 ttyU3.lock From dmesg: Root mount waiting for: usbus2 ugen2.3: <FTDI USB - Serial> at usbus2 uftdi0 on uhub7 uftdi0: <USB - Serial> on usbus2 Root mount waiting for: usbus2 ugen2.4: <FTDI USB - Serial> at usbus2 uftdi1 on uhub7 uftdi1: <USB - Serial> on usbus2 ugen2.5: <FTDI USB - Serial> at usbus2 uftdi2 on uhub7 uftdi2: <USB - Serial> on usbus2 Root mount waiting for: usbus2 ugen2.6: <FTDI USB - Serial> at usbus2 uftdi3 on uhub7 uftdi3: <USB - Serial> on usbus2 random: unblocking device. ugen0.2: <vendor 0x046a wired keyboard> at usbus0 ukbd1 on uhub1 ukbd1: <vendor 0x046a wired keyboard, class 0/0, rev 2.00/1.03, addr 2> on usbus0 kbd3 at ukbd1 root@db2:/usr/local/etc/rc.d # kldstat Id Refs Address Size Name 1 25 0xffffffff80200000 20647f8 kernel 2 1 0xffffffff82266000 381080 zfs.ko 3 2 0xffffffff825e8000 a380 opensolaris.ko 4 1 0xffffffff825f3000 adf0 uftdi.ko --- PGP-Key:29E99DD6 ☀ computing @ chaos claudiushelp
