Correct.

To expand: The documented interface for CAPI 2.0 applications is the
shared library libcapi20.so. Originally that library just interfaced to
the kernel CAPI subsystem through /dev/capi20. Later it was extended to
support different access paths to ISDN devices:
- via /dev/capi20 and kernel CAPI as before
- over the network and a remote CAPI server running rcapid
- over the network to FRITZ!Box router via AVM's CAPI-over-TCP service
- last but not least, via the mISDNcapid daemon and mISDN

Of course this cuts off anything that doesn't pass through libcapi20.so,
including applications that (against the standard) access /dev/capi20
directly but also the capidrv.ko i4l compatibility shim.
