How many serial ports can be configured on the HP400s & HP433s workstation under Domain/OS? A HP engineer informed me that this is limited to the number of AT slots that are available in the ISA/EISA bus cage. Only options I have are either using the Serial/Parallel sold by HP (therefore I can only have 7 ports :-() or writing a driver for the Stallion card (over 32 ports :-)). Has this been done before? I am very interested in hearing any other options. Would you please email your response. Thanx in advance, Sebastien. -- +-------------------------------------------------------------+ | Sebastien Hadjifotis Manager - Research and Development | | Eastek Limited. | | 476 St. Kilda Road, Melbourne, Victoria 3004, AUSTRALIA. | | | | ACSnet : snh@eastek.oz | | UUCP : uunet!eastek.oz.au!snh | | Phone : +61 3 866 2566 Fax: +61 3 820 9440 | +-------------------------------------------------------------+

It's very difficult to write a tty driver for Domain/OS. You need to use
either the unreleased tty trait, or System V streams. Or maybe ptys and a
server process. I don't know of anyone outside Apollo who has done this.bruce@dannet.UUCP (Bruce Hill) (01/11/91)

Up to four of these can be put into an HP400s. However, if you want to use the Domain Token Ring card, you'll have to give up one of the four ISA slots.

Danford Corp. has marketed a couple of different Multibus and AT-bus (ISA) cards for adding RS232 lines to the Apollo workstation line. I seem to remember getting a letter from them that talk about their supporting the new HP/Apollo 9000 series 400 machines. Danford provided software drivers for their cards. I'd try giving them a call. I've only got the number of the Massachusetts sales office -- 617-861-6197 -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
