For example: IT $ tcpip show version HP TCP/IP Services for OpenVMS Industry Standard 64 Version V5.6 - ECO 5 on an HP zx2000 (1.50GHz/6.0MB) running OpenVMS V8.3-1H1 As usual, that new copy+paste technology can be more reliable than older, more manual methods. > I have the latest OVMS 8.3 Patch Bundle V18 installed.

Which I don't.) > It fails at the bind() call. [...] Fails how, exactly? errno = ? A complete problem description is a joy to behold. Partly because of its rarity, I suppose.
