Device ttyAMA0 is locked.

Rak2013 is working just fine. Service starts on boot up and runs just fine. I have no issues with the functionality of the device just not sure why I can’t talk to the modem. If the service is running then the serial port is locked. If it is not running then I somehow there isn’t a ttyAMA0 device?
pi@hostname:~ $ ls /dev/
autofs loop4 ram2 tty17 tty41 tty9 vcsm-cma
block loop5 ram3 tty18 tty42 **ttyAMA0** vcsu
btrfs-control loop6 ram4 tty19 tty43 ttyprintk vcsu1
But as you can see i still have it in my /dev when I look at it. Any thoughts on this? I’m at a loss. Thanks.
