[RS232] how to use InputStream and OutputStream

hi
i am using javax.comm
i get input and outputstream
              try {
               out  = serialPort.getOutputStream();
                        in    =serialPort.getInputStream();
              } catch (IOException e) {
                    }but i can use only write(bytes[]) and read(bytes[])
i would use println and readln .. how can i do that?
thanks in advance, nik

    <b><u>Questions -</u></b> <br>
    <br>
    1) Are inputstream and outputstream objects totally independent of eachother ?<br>
    2) Will the change in the position of the "inputstream.close()" method as shown above, affect the writing of the file to the file system ?
    In other words, will the outcome of an "FileOutputStream.write(), flush() or close()" depend on when the inputstream object is closed as seen in code snippet (2) ?<br>
    3) Assuming that the output buffer is flushed, will any data that you try to write using the OutputStream.write() method, be written to the outputstream target (whether a file, or response object), irrespective of whether the inputstream is active at that point of time ??<br>
    <br>
    Thanks,<br>

    Hey kaj...Do you have any idea about the "not normal"
    situations in which case the input and output streams
    might influence eachother ? ;)Those cases are when both streams comes from a resource which closes both streams when one of them is closed. It's very rare to see, but I've seen some socket implementations which does that.

  • How to use IDOC and RFC adapter in 1 scenario?

    We have AAA field and BBB field and we want to send AAA field to receiver sap system using IDOC adapter and BBB field to receiver sap system using RFC adapter. But how to use IDOC and RFC adapter in 1 scenario and how to map and  what are the design and configuration objects we require to create?

    To achieve this you have to use
    Two Interface Determinations
    Two Communication Channels (IDOC & RFC)
    & Two Receiver Aggrements.
    Use the Enhanced Interface determination and give your conditions there. Based on you condition your interface mapping will be triggered and data will be sent to IDOC & RFC respectively.

    hi,
      You cannot use the logical and  or condition together at the same time in SQL statement. Sachin is correct while using the and and or in the same condition. You can get the data using or condition in SQL statement, and then use the delete statement of internal table using the end condition. please find the following code for the same.
    select *
      from dtab
    where cond1 eq 'A1'
         or cond2 eq 'A2'.
    if sy-subrc eq 0.
      delete itab where cond1 eq 'A1' and 'A2'.
    endif.
    regards,

  • Query: how to use structure and selection and what's the difference between

    Query: how to use structure and selection and what's the difference between these two?
    Would be appreciated if some experts here give examples to demenstrate on how to use structure and selection in query and what's the difference between these two?
    Thanks in advance!

    Hi Kevin,
    1. Well by default all the KF that you include in your query go into a Key Figure Structure. You can additionally have another structure for defining how your chars are laid out. A common example is a Calmonth structure where you have selections for 12 months, quarers and YTD values. This would be a char structure with different selections (for each month, qtr etc)
    2. Yes, a selection with a KF is the same as restricting a KF. You can use am RKF is you have one on the left hand side, or if you need to do this locally in the query, right click the structure and choose New Selection, then proceed to choose your KF and reqd char values.
    Hope this helps...

  • Workflow Components : how to use SPLIT and JOIN ?

    Dear all,
    Because a Transition does not have any return of result, do you know how to use SPLIT and JOIN components ?
    <activity name='"xyz">
    <Transition to='act1'>
    </Transition>
    <Transition to='act2'>
    </Transition>
    </activity>
    In this above example, the second transition towards act2 is never called (i.e. there is no condition for the first transition) because there is no return of result for the first transition.
    Unfortunately, I didn't find any documentation about the SPLIT and JOIN workflow components. Do you have some information about these components ? How to use them ?
    Thanks a lot.

    <activity name='"xyz" andSplit='true'>
    <Transition to='act1'>
    </Transition>
    <Transition to='act2'>
    </Transition>
    </activity>
    The "andSplit='true'" will cause it transition to both act1 and act1.
