Problem in reading data from serial port

[Former Member]

Hi Experts,

    I am using a function module mentioned in the following link to read the data from serial port( from weighing Machine).

     http://scn.sap.com/thread/1766170

    If I am running the function module  in the debugging mode , the data is getting retrieved,but
    is failing to read the data in the direct execution mode..

    following are the routines which  run in debugging :

                      1.       PERFORM open_port USING commport settings.

                      2.       PERFORM read_port CHANGING input.

     any answers please..
