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?

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.
