after many operations eibcontrol returns invalid values when read values with "read" or write (in this case the answer string).
example: lamp is off (0)
write 1 on lamp group adress. now the lamp is on (1), but the answer string of the current status of the group adress returns still 0, same with the normal "read" command.
i can deliver more details if necessary. please give me a info with information / debug you need.
i can reproduce this problem. when driver/server is restartet, the problem is solved until the next hundred values are written/read. then it accures again.
