If the source machine is not an IBM host, this type of communication is only possible if both LU6.2
products support peer-to-peer communication (PU type 2.1).
Calling an external RFC program is not possible because, at present, no SAP RFC SDK (Software
Development Kit) is supplied for platforms accessible via LU6.2.
All other requirements are the same as those already listed for R/2 -> R/3 communication.
