The first release of the universal forwarder for HP-UX 11.22 / 11.31.
There are no releases which specifically target the very first release of HP-UX 11.
However, the whole topic of HP-UX versioning is fairly complex with patch levels and revisions, and it is difficult for me to comment on this with absolute authority of what might work. It's certainly true that 11i v2 11.22+ and 11iv3 11.31+ are the targets.
