I recently bought myself a HP Visualize c3750 specifically to try out HP-UX (which I have never really used), I got it with a CD set of HP-UX 11 that I boot the machine from to install.
I have no gfx adapter in the machine so I run an IBM InfoWindow II 3153 serial terminal attached to serial 1. Everything I expect to display is displayed via the terminal.
When I start up I use this guide:
Installing HP-UX 11i
Everything seems fine until its time to choose terminal emulation. I started up in ibm3151 mode at first and after the initial choice of terminal I get (as you might expect) a lot of garbled text and then the installation fails when it can't determine screen size.
I configured the 3153 for VT 100 and Wyse 60 emulation but after booting and getting the "chose terminal emulation" during installation screen I can't input anything. It's very frustrating. If I switch back to ibm3151 I can input at this screen but alas that gives me garbage on the next screen before I can switch back to the correct emulation mode.
I booted the machine with a OpenBSD/hppa install ISO and that lets me chose VT 100 just fine and continue the install.
Any suggestions welcome, I'm stumped and I've googled this sideways without finding a solution.
Edit: Clarification - no matter what terminal emulation I set on the 3153 it works fine in the BIOS (forgive for not knowing the correct term for the BIOS of the machine) it's after booting HP-UX at the very first prompt that it just stops accepting input.
