[] I am going to set up a 386 PC based UNIX with dumb terminals connected. I really appreciate any information on the multiport board. My questions are 1. How many different types of board are available in the market right now? 2. Which company is in the leading position right now? 3. How hard it is to set these up? 4. Pricing? 5. Do you encounter any problem with your current board? 6. Whatever question you have in mind that I haven't thought about. :-) Any info will help. Thanks. Shyh-Pei Yen USENET: spyen@cup.portal.com

BEWARE OF MAXPEED!!! The company I work for recently bought a 386 to be used as an Accounting Computer. We purchased SCO Unix as the operating system. We also had purchased an 8 port Maxpeed i/o card to hang terminals off of. The original recommendation was that we should buy a Digiboard (i.e. stick with something almost guaranteed to work), but in an effort to try and save money the Maxpeed was purchased. Well, guess what...by now it has cost us at least 5 times as much as if we had just bought a Digicard up front. After installing the Maxpeed card we had nothing but problems. The computer would crash any where from 1 to 5 times per day. Myself and our resident "hardware guru" spent many many hours switching cards in and out and changing the system configuration and even switching the entire machine, in an effort to find the offending piece of hardware. Well, after the process of elimination (logic seemed to quit working after X number of hours :-)) we found it to be the Maxpeed card. We called Maxpeed and they sent us more current drivers, which reduced the number of crashes per day from 1-5, to 1-2. But the machine was still very unreliable!!! So, we bought an 8 port Digiboard and installed it and have not had one single problem with the system crashing. As long as I'm dumping on Maxpeed, I'll mention one more thing... When we originally received the i/o card from them the documentation was very unprofessional. It gave a "fly by night" appearance. The documentation that showed the pinouts of the serial connector had been corrected in pen or pencil and then copied on a copying machine! Moral #1: Don't use Maxpeed 8 port i/o cards with SCO Unix. Moral #2: Don't always pick the cheapest route, you may find it's not so cheap. Bruce -- Bruce M.

We > >I looked at maxspeed a couple of months ago - and at the time they >didn't even support hardware flow control.. I have followed this conversation with some interest recently and finally MUST respond. First, Maxpeed has a number of different cards with a series of available drivers. I have been installing these in systems running ISC 2.02 and 2.2 for a little over a year. Both the series 1 and 2 work very well under most, if not all applications. Specifically, multiple cards work as described (4 cards with 24 ports are running in one system with some terminals placed up to 400 feet away). Transparent printing works correctly (using Wyse 150's). Multiple trailblazers on one card work well. And, even though I have seen postings to the contrary, VP/ix works great on the Maxpeed cards. The RTS/CTS problem is one that tends to plague many serial board manufacturers. Depending on which drivers are installed, Maxpeed does support RTS/CTS but on a shared port basis. In this configuration, ttyaa and ab become one modem port and one 3 wire terminal port (in other words, you do completely lose ttyab, just DCD and DTR, which become RTS/CTS for ttyaa). Most importantly, these cards install (series 2) in systems with 16 megs of memory (many do not allow the drivers to be placed in high memory). Lastly, I have found the people at Maxpeed to be wonderful to work with, from technical support to sales. They have always done what they said they would do and have bent over backwards to accomodate the customer. This is VERY important and cannot be stressed enough. To top it off, the price is good and they rapidly honor warranty repair even if it is not their fault (there are some lightning strike stories...). SO, what really bothers me the most about these several Maxpeed postings (including Conner's FAQ), is that after evaluating 4 other serial card manufacturers, the Maxpeed is SUBSTANTIALLY better. This is a separate subject area, though. Someday I will try to put together these various tests into something coherent and post a "Serial Board- Watch Out" posting. [ I have no affiliation with Maxpeed except to be a very satisfied customer. The systems tested with this card include Compaq as well as others with a variety of configurations: 4-16 Megs of memory, cacheing and non-cacheing, transparent printing used daily in several different business environments, up to 24 ports, all with VP/ix tested, up to 6 modems running on one card simultaneously, etc. ] Gary Lewin gary@mic.lonestar.org

So one port will have the hardware flow control using additional lines from another port - while the other port (the one who gave up the additional lines) becomes a 3 wire terminal port - so if I want to support 8 modems, I need 16 ports (if I go with maxspeed) and I am stuck with 8 terminal ports - even if I don't need them. Hmmm.. With my Computone (and from what I hear with the Comtrol Ultra and latest Digiboard) if I need to support 8 modems, I get 8 ports - not 16. The Computone works great with hardware flow control on multiple modems. I must be missing something here - I don't see why to buy twice as many ports as one needs to run hardware flow control.. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {larry@nstar, uunet!sco!romed!nstar!larry, nstar%larry@iuvax.cs.indiana.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)

Would someone be so kind as to post a source for that "generic" (MMU-xxx?) 4-port serial card that was discussed recently? I know a source was posted, but that article has been expired, so I am out of luck. I believe it sells for around $115.
