Unfortunately, I don't have their address. At least you >have a clue! So does anyone know how I can contact BlackBox Inc.? This is an important bit of info, because MANY serial devices out there cannot work with NeXT without it. It is a frustrating situation. I never thought the wonderfully designed Cube could have such a blatant problem. It's like building a Ferrari, then forgetting to put a needle on the fuel gauge. Also, I mentioned earlier that XON/XOFF doesn't work at 19200. Another very annoying bug. It probably can be fixed with a patch. I am using system 1.0 (not 1.0a), and I am wondering if people who have 1.0a have encountered the same problem? It is a hard one to test. You have to connect a device like say printer that prints slow enough to need XON/XOFF to work at 19200, then try to see if it will run. If anyone has a patch for this bug, I would really like to hear about it!! ---------------------------------------------------------------------------- Internet... it isn't just a network, it's a Way of Life.

Box 12800 Pittsburgh, PA 15241 Order: (412) 746-5530 Technical Support: (412) 746-5565 I suspect that the device you want from Black Box is their Communications Adapter Plus (CAP), which has two RS-232 ports that can be individually programmed with different speeds, code structures, transmission modes, word structures (parity), or flow-control protocols. However, the flow-control options listed in the catalog for this device don't include RTS/CTS hardware control, but DTR/CTS (????, a typo?). Call them. > > ---------------------------------------------------------------------------- > Internet... it isn't just a network, it's a Way of Life. > -Dan Hall =_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_= Dan Hall | CSS/NSG Transmission Products Engineering Digital Equipment Corporation | ARPAnet: hall@state.enet.dec.com Continental Blvd. | EASYnet: STATE::HALL MKO1-2/H10, PO Box 430 | Usenet : ....!decwrl!state.dec.com!hall Merrimack, NH 03054-0430 | NET : (603) 884-5879 =_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=_=

They seem to have two phone numbers. 412-746-5530 for placing orders, -5565 for tech info. Call one or the other and ask for a catalog. For future reference: There is a wonderful publication called the Electronic Industry Telephone Directory. Electronics parts distributors like Arrow and Hamilton/Avnet give them away. If you're at a school, the EE department should have a copy. --- Jamie Hanrahan, Simpact Associates, San Diego CA Chair, VMSnet [DECUS uucp] and Internals Working Groups, DECUS VAX Systems SIG Internet: jeh@dcs.simpact.com, or if that fails, jeh@crash.cts.com Uucp: ...{crash,scubed,decwrl}!simpact!jeh
