TTerm Pro's latest version uses NS/VT
May 14, 2014
As we reported yesterday, the TTerm Pro app for HP 3000 emulation got an enhancement this month, one that makes the software very unique. NS/VT protocol support isn't exactly rocket science, but its not straightforward, either. The history of the 3000 is strewn with terminal emulator makers who didn't get this aspect all figured out.
Our ally Jon Diercks, who's the author of The MPE/iX System Administrator Handbook, updated his iPad app and gave the new 1.1.0 version a test. The short report: NS/VT seems to work, at first glance. Diercks added a second test to the first one of the app. He connected his iPad to the HPA202 freeware version of CHARON. With his exam, an HP 3000 terminal emulator was talking with an emulated HP 3000. He offered the screen shot above as proof.
Well, the 30-second report is ... it works! I fired up Charon, copied my previous TTerm telnet profile and changed to NS/VT, and the logon prompt came right up. The :SHOWVAR command above proves that NS/VT protocol is in use. I also launched NMMGR just to verify block mode still looks okay. I might play with it more later, but that's enough to satisfy my curiosity for now.
It's a marvel to consider how MPE has been carried into the future with this combination. The iOS operating system on the iPad is certain to have a longer life where it's improved than the alternatives based on desktops. By that, I mean I believe iOS has "got legs," as the saying goes among theatre people when they talk about a long-running show. You don't need a PC and Windows any more to emulate a 3000 terminal.
And with CHARON, you don't need the 3000 hardware anymore, either. All that's left is MPE and IMAGE, the bedrock of what we know as the 3000 experience.
