We have an HP 9000 Model 236 running HP/UX 2.1 Our problem is that whenever we send a file to the printer (an hp 2671G, hooked up to the internal HP-IB) the keyboard on the console becomes inactivated. The only solution we have found so far is to re-boot. However, the system is not crashing. The system keeps running and it's business like usual from the terminal. It does not matter who or what sent the stuff to the printer. We have tried killing the shell of the user on the console. This doesn't work. We can echo to /dev/console. The internal HP-IB is select code 7. The printer is set at device address 1. SRQ is disabled and listen always is off. When the print job is sent it functions normally. Please note the system does not crash, we just lose all use of the console. Please help. We are a computer science club and cannot really afford the high price of bringing someone in to fix it. We have a lot of bright people around that could fix the thing if they knew where to look. --Jim Boritz for the Computer Science Club {allegra,decvax,utzoo,clyde}!watmath!orchid!csc

I had the same problem with my Model 217, but only if I had a disc drive on the same HP-IB as the printer (and only when the printer was a "simple" HP-IB printer, rather than one using AMIGO pacing protocol, such as a 2631B). This was a bug in that version of HP-UX. It was corrected in revision 5.1 (which was the next revision after 2.3). > We are a computer science club and cannot really afford the > high price of bringing someone in to fix it. It would be fairly expensive to fix, since an upgrade to 5.1 on the Model 236 requires swapping out your MC68000 CPU board for an MC68010 board, in addition to acquiring the software itself. If you have a spare I/O slot, it might be cheaper to add a second HP-IB card (98624A). If you have a serial port available (98626A, 98628A or 98644A card), it might be less costly to replace the 2671G with a generic serial printer.
