We have been running 386/ix 2.0.2 on our Compaq 386/20 for several months. Since upgrading from 1.0.5, we have not been able to get satisfactory inbound uucp performance using our Telebit Trailblazer. The X5 driver update has not helped at all. After months of oversized bills from uunet, spent mostly on stalled connections, we give up. We no longer want to know why our configuration worked great under 1.0.5 and lousy under 2.0.2. Some of you have reported that similar problems went away as a result of the improved support for 16550A UARTs in the X5 update. My question now is: Can anyone with a hardware configuration like ours recommend a specific high-performance asynch board with 16550A chip(s) that works well under 2.0.2? We don't need lots of ports, and would prefer a board with RJ-45 connections. We mostly just want to see over 1000 bytes/sec like the good old days, and the extra bucks spent while trying to find a solution could have paid for a good board. Now a question about support for 386/ix: In the process of trying to find a solution for the above problem, we first turned to our distributer for help. He went to ISC and came back with nothing, until I was able to give him specific suggestions which came from this forum. After waiting for the X5 update (and then waiting to get a complete copy of the accompanying documentation after two partial copies), and then having no improvement, I called ISC technical support (in Santa Monica) myself. What I got was a lecture on how they only provided support for their distributers, but that I could send e-mail and they might look at it. (I did; no reply so far.) Several notes here recently have been very complimentary of ISC tech support for 386/ix, so the question for those of you who feel that way is, where are you calling and who are you talking to? Are you paying for support? I asked the person I spoke to about this, and he said that support was only available from the distributers. (Our company sells software to OEMs and O/S vendors who provide all end-user support, so I am well familiar with this concept. My interest in asking these questions is not to vent frustration, but just to try and get a solution to our problem. Any help is appreciated.) -- Jerry Toporek ======================== `` '' =============================== jt@mentat.com < @ @ > Mentat Inc. uunet!mentat.com!jt ( > ) 1020 Pico Blvd Suite B (213)452-5666 \~/ Santa Monica, CA 90405

The Bell Tech ICC (and maybe the ACE, not sure) use RJ45's and claim to handle the load. I have an ICC and have downloaded data at full 19.2k, but it was not a news feed. I haven't tried the ICC with my news feed because I havn't had time. I also have a Maxspeed 8 port card (list 795, but available for around 500 from Tangent Computer Inc.). This card has 6 line RJ-11's, but I just built short RJ11 to RJ45 conversion cables and use RJ45s for all my office cabling. I have been unable to get the Maxspeed card working at 19.2k, but I get acceptable performance (around 850cps) at 9600 baud. Maxspeed has been helpfull and claim that they have other customers that do not have a problem with 19.2. They even gave me the number of one of thier customers, but I have yet to call the customer because I dont have the time. -- +-----------------------------------------------------------------------+ | Conor P.

We >mostly just want to see over 1000 bytes/sec like the good old days, For dumb ports I've had good luck plugging in NS16550A uarts into an old Multitech multifunction board just used for it's serial ports. Now I'm also having VERY good luck with an Equinox Megaport 24 port board. It uses no off the shelf uarts. I get the Telebit Trailblazer transfer speed you are looking for and I've freed up a slot in the motherboard and saved interrupts too! Also, it has many connector options.
