Hello Patrick,
I am currently working on my master thesis in computer science in which
I'm trying to exploit you great open source software linux DECT-Stack.
I plan to use it for controlling a Com-On-Air PCI ISDN card
(Dosch&Amand). However, I'm facing problems with operating libdect,
dectmon. To be more precise, after installing software and trying to run
it I always get the following error message:

and for any dect-command in asterisk:

Since my master degree depends highly on successful usage of your
software I want to ask you for help and would very appreciate it.
It would be very nice if you could give me an advise on how the problem
can be solved.
Please let me know if you need additional info, esp. in case the error
text is not enough for you to be able to analyze the error.
Thank you in advance!

Did you install the corresponding kernel, enabled the DECT kernel stack
during compilation, and load the modules?
Can you execute strace src/dectmon?

Did you install the corresponding kernel, enabled the
DECT kernel stack
during compilation, and load the modules?
Can you execute strace src/dectmon?

module has been loaded?
Did you compile DECT support as a module? If so, does dect show up in
lsmod?
