I am interested in running DOS programs under UNIX, probably Xenix, on a 386 machine using something like VP/IX. I was told by the SUN salesman, whose 386i will also run DOS, that programs using a lot of interrupt driven IO will run slowly. They say it will be faster in the future but there is a lot of overhead in the interrupt emulation. Does anyone have experience in using interrupts driven IO on any of the DOS emulators for UNIX/Xenix ? I am looking at about 9600 baud on a serial port and maybe some type of DOS networking on ethernet or arcnet. Thanks in advance. John C. Tompkins

Tompkins I have been running VPiX under Xenix386. The following statements are what I have noticed about the product. 1) The DOS programs run nearly as fast under VPiX as under MSDOS on the console. If the programs run on remote terminals, the reduced baud rate is definately noticeable when output by the program is required. 2) You need MANY megabytes of memory in your computer for proper operation. I would strongly suggest a minimum of 4 megs to start if you have other Xenix programs running at the same time. 3) Not all terminals are supported under VPiX. This may cause problems for you. Tou summarize, the product is excellent and is well worth the money. Sanford <sandy> Zelkovitz

[ DOS comm prgs under VP/ix ] We've tried VP/ix, but *no* comm prog works under any reasonable baudrate using a *protocol*. (Just terminal emulation is ok) It must be noded that I don;t have the final version of VP/ix yet, but I fear the worst. Richard (...!mcvax!neabbs!richard)

The final version of VP/IX corrects most problems I encountered with 1.0. It also supports comm programs up to 2400 baud. Jonathan Bayer Intelligent Software Products, Inc.

Yes, the final version is much better. I use it with a comm program at 9600 baud (and ~ get 2400 baud throughput, but anyway....)

In today's world of TB+ modems (and its similar companions in the 9600 baud world) are we really to consider 2400 to be a *reasonable* baud rate? --jim ------------- James B.

In todays world of TB+ modems and protocol spoofing, are we really to consider DOS to be a *reasonable* working environment? If you really need a chatty little modem program, use pcomm under SV/386 and forget about DOS. As for me, the only protocol I use these days is uucp-g. The only use for VPIX is programs that can't be found for UNIX. Stuff like Locust 1-2-3, or Weirdstar or AutoCAD. There are enough PD options for terminal work that there's no point waiting around for DOS. Term programs are a particularly bad case... under DOS they're one of the biggest CPU hogs. Under UNIX they're one of the lightest loads. -- Peter da Silva `-_-' Ferranti International Controls Corporation "Have you hugged U your wolf today?" uunet.uu.net!ficc!peter Disclaimer: My typos are my own damn business. peter@ficc.uu.net

In today's world of communication programs available under Unix (Xenix) i think it is very reasonable when someone, who still insists to run a DOS based communication program on top of Unix, still gets 2400 baud throughput. There is a LOT of overhead involved in accessing devices, so you get what you deserve.

Bell Technologies claims their ACE driver (v0.4 beta) does, but >it doesn't work for my client using it on an Everex 386/20. Connect-Tech Inc's "Intellicon" board - 2, 4 or 8 ports. Computone's Advantage and Intelliport boards: 2, 4, 8 or 16 ports. We prefer the former because they're simpler, cheaper and don't get in the way. The latter has some pretty spectacular features (transparent AUX printer handling, multiple virtual screens, and "keyboard macros") which would be handy in some applications, but not for others. As far as reliability/compatibility goes, we've had no problems whatsoever with the Connect-Tech boards - many months of solid dependability with VP/IX (eg: DOS WordPerfect, Symphony and 123) and UNIX (386/ix). One of our customers has an Intelliport board on Xenix - once we managed to demuck the configuration screwups his previous consultants introduced, it appears to be working quite well (VP/IX, UNIX WordPerfect etc.) However, there have been a few circumstances that have led us to believe that individual channels can get hungup - though we haven't been able to confirm them. -- Chris Lewis Ferret Mailing list:{uunet!attcan,yunexus,utzoo}!lsuc!gate!eci386!ferret-request {uunet!attcan,uunet,utgpu,yunexus,utzoo}!lsuc!ecicrl!clewis (or lsuc!gate!eci386!clewis or lsuc!clewis)

We checked a few out before shipment, and didn't see any problems with it at all. I've no idea just how efficient they are though. Aren't those 'cat eyes' patterns that the LED arrays play on the Computone boards rather "interesting"? :-) -- Karl Denninger (karl@ddsw1.MCS.COM, ddsw1!karl) Data: [+1 312 566-8912], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.
