I'm curious as to exactly what's in a D320, could you add this to the hardware database at http://www.thepuffingroup.com/parisc/hw.html? The console problems you're having are actually global to every machine, not just yours. I think we've solved several console problems, so you may want to try again. > Now the interesting thing in a D-Class with an AP card installed is that > the RS-232 connector on the back of the machine is dis-connected from > the LASI serial hardware and connected to the AP card hardware.

That's true of console output, since we can just use PDC calls. However, it's difficult or impossible to do console input with PDC because we'd have to poll for new characters using PDC_CIN, which is a bit of a pain. - Alex -- Alex deVries Director of Professional Services The Puffins at Linuxcare
