One other gotcha, in addition to the ones Rob mentions: (4) Although IBM recommends that responses to console commands be written in a single message, most applications ignore this (conspicuously VTAM). So, you should be prepared to receive multiple response messages matching your CART (look in field MDBCCART of the MDB), with perhaps a delay in between. In some cases (like D NET,EEDIAG) the responses may be separated by a minute or more.
