I think you are thinking at too low a level. Let's assume you build a piece of code (Channel) for talking and listening to your serial connection. This jPOS Channel will use a packager to interpret the bits and bytes arriving on the Channel. The result of a call to receive is an ISOMsg, the parameter into send is also an ISOMsg. Field 7 in an ISOMsg (msg) can be examined :- String dateTime = msg.getString(7); And field 39 could be set thus:- msg.set(39,"00"); Thus the hard work (ignoring - for now - the serial port handling) is getting the packager to match the structure of your messages. Do you have a technical specification of the messages you are wanting to send and receive that goes down the the level of each field? Andy provided an excellent post in jpos-users (on google groups) in response to a (I think) similar question:- http://tinyurl.com/37vmtb Join and search jpos-users and I think you will find questions and answers more relevant to your handling needs. -- -- Mark
