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
