[Simh] EXT :Re: Simh and OpenVMS Integrity V8.4 Network Support issues

[Hittner, David T (IS)]

There is a known problem with the pcap networking implementation on OpenVMS IA64 8.4.
The original TCPIP$LIBPCAP simulation delivery with 8.4 (TCPIP 5.7) was quite defective, and did not support enough pcap interfaces for SIMH to work.
HP has since issued TCPIP 5.7 ECO3, which I'll try to get some time to test in the next few weeks.

Matt also produced an Integrity port of the Alpha-only PCAP-VMS, which I haven't fully tested either.
SIMH worked with Matt's port for most of the networking, but I didn't have time to do a full-blown qualification.

Which PCAP port did you test SIMH with?  HP's port or Matt's?

When I did the port to I64 I tested on V8.4, but it was on an rx4640. I have had a report from someone else with an rx2600 experiencing the same problem. Perhaps it is something to do with the brand of network card? I have access to some other Interity systems (rx1620, rx2600, rx3600) so I'll do some testing on those to see if I can reproduce the problem (it may be a few weeks before I get chance to do this).

I'm fairly sure I fixed all those bugs so if this is still happening then it may be that one of the LAN driver calls is not returning (IOLOCK8 spinlock is aquired/released either side of each LAN driver call)
