1. z/VM 5.3 allows you to ATTACH the real HMC ASCII console to a guest. We do that so that you can test how things behave if you run that Linux guest in an LPAR, or use it to repair a Linux guest with a damaged network connection. I don't understand your point about nothing exploiting it; it's for people. Login to your HMC and start the ASCII console for the z/VM LPAR. Then go to CP and ATTACH it to Linux. Make sure your Linux configuration includes enablement of BOTH the 3215 and the full-screen mode h/w console, with the 3215 as the preferred console. (If the ASCII console isn't attached with Linux comes up, I don't know if you have to do something to get him to initialize it on ATTACH or not.) 2. I don't understand the "arcane and fragile" comment. Someone who hasn't been educated on mainframe system architecture will be stymied by the HMC, I'm sure, but it's all window-y and point & click. How is that arcane? I never hear of an HMC failure, though I *do* hear of the occassional Support Element (SE) failure, but that's why there are two SEs in the box. And I believe there's support for multiple HMCs as well. Maybe you're referring to the "F-R-A-G-I-L-E" on the shipping container? That's the country of origin, pronounced "fra-gee-lay". :-) I understand that what people want is the ability to putty into the *VM* system and be able to use the VT220 suppport to login and access the Linux virtual machine console. Oh, and you still want to be able to issue #CP commands, not just Linux hcp commands. A worthy goal.
