Hi, I'm trying to use serial port but the system says device busy. daemon# cu -l /dev/cuad0 -s 9600 /dev/cuad0: Device busy link down daemon# uname -an FreeBSD daemon.micom.mng.net 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #0: Mon Jan 14 16:49:57 ULAT 2008 tsgan@daemon.micom.mng.net:/usr/obj/usr/src/sys/GDAEMON i386 It seems like no other program is using serial port. How to check whether something is using serial port? Any idea? thanks, Ganbold -- If you think the problem is bad now, just wait until we've solved it. -- Arthur Kasspe
