OK.
I do have one more question.
If i open isdn connection and directly after that i open some data 
logger i can not close the same isdn connection ** automatically**  on 
data logger closing. Basicaly, i close data logger program but isdn 
connections is still connected.

Shortly:
open isdn connection
open datalogger
close datalogger
close isdn connection.

When program starts, he opens isdn and when i X-it the datalogger, isdn 
should be closed and not before.
