I had trouble sending this the first time, so it may be replicated. Sorry about this. I don't have access to the 1988 X.400 MHS standards, and I need a clarification wrt to P7 fetch operation. The Omnicom course material for 1988 X.400 that I have says the following: If the fetch operation is performed successfully, the MS sends to the UA a ReturnResult APDU with the invoke identifier value from the Invoke (fetch) APDU, and a set containing the message as the return result. My question: Is the message returned a P2 PDU? My current thinking is yes. If not, what is it? Is a message submitted by the remote UA also a P2 PDU? My interest comes from trying to make sure that an arbitrary UA on a remote m/c, e.g., a PC, that implements P7 based on X.400 standards can talk with an MS/MTA that also implements P7 based on X.400 standards. Also, in case MS is remote from the MTA - Is the message submitted by MS to MTA or delivered to MS to MTA a P2 PDU? Thanks in advance for your responses.
