But it is impossible for ISDN. The others were right, ISDN is
digital and there is no way you can flash this digital line. ISDN
devices utilize other means to do things such as HOLD and
TRANSFER, i.e. Q.931 messages as mentioned.

In minicom ATD! gives an error, because it is not implemented in
ISDN4Linux of course.

I would have to switch to CAPI but the driver doesn't compile
cleanly yet.
