Before you can connect to an AS/400 using the MPTN interface, the AS/400 must be set up to use TCP/IP. For your AS/400 to
communicate using TCP/IP, it must be running OS/400, Version 3.0, Release 1 (or later).
Note: This is an absolute requirement. Earlier versions of the operating system do not allow you to properly configure TCP/IP addresses
for either your AS/400 or your client workstations.
