BMW edc15cp35 check for correct ISN

[kombinator-318]

Hi,

can someone quickly tell me how I can check with tool32 if the DDE received the correct ISN, or that communication is disturbed. I found EWS_STARTWERT and EWS_EMPFANG
there I guess it could be STAT_EWS_WERT , response is 1
or EWS_STATUS_VALUE, response 5

or is it somewhere else?
I use D60M57D0.prg

thanks for help
