I know this might sound like kludge-city, but it would still be great
if it would work:
We would like to know if a MS-DOS program running under VP/ix in
SCO XENIX can talk to a serial port, say COM2. But more than that!
Could we connect a null modem cable between COM1 and COM2, and then
have a XENIX process talk through COM1 to to the VP/ix application?
We would like to be able to use one machine to demonstrate our PC
software product (which would in normal circumstances be used on a
separate PC with a modem to connect to our XENIX host) all in one box,
rather than having to drag a PC and a serial cable along with the XENIX
machine whenever we go on the road.
Would VP/ix be able to handle that?

VP/ix allows access to serial ports. I haven't actually used the serial ports under VP/ix, but the manual claims you can. One thing to be aware of, if you are runnign VP/ix in MultiScreens on the console and switch from the VPix screen to any other screen, your VP/ix process stops. j |%|John Lawitzke, Dale Computer Corp., R&D |%|UUCP: uunet!frith!dale1!jhl Work |%| uunet!frith!dale1!ipecac!jhl Home Inquiring minds just wondering. |%|Internet: jhl@frith.egr.msu.edu [35.8.8.108]

See section B.6 of the update notes for update A (1.0 -> 1.1). You can continue processing off screen tasks, but only if you have a cga, herc, or mda installed. Too bad if you have an EGA or VGA. -Richard L. Goerwitz goer@sophist.uchicago.edu rutgers!oddjob!gide!sophist!goer

Only for VP/ix 1.00 and 1.01. The latest release (Update A) is 1.1, and has an option to let VP/ix run even if it is on a non-visible Multiscreen.

In the new update to VP/ix this is supposedly fixed for some displays. If you can live with one of those the process will run on. I have *not* tried it, since VGA is not a supported display type for continued operation. Be warned, it has been reported that typing as UNIX command, such as ls, in VP/ix with the update installed will hang the system. I don't have the guts to try it. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.

>your VP/ix process stops
Does it "die" or just "feeeze" until you come back to whatever Alt-Functionkey
multiscreen the VP/ix application is running on?
oops.. make that "freeze"...

VP/ix doesn't handle high baud rates (38400) very well - like when doing Zmodem transfers. -- Larry Snyder uucp: iuvax!ndcheg!ndmath!nstar!larry The Northern Star Usenet Distribution Site Notre Dame, Indiana USA

As others have pointed out ver 1.1 doesn't halt the job on mono, herc, or cga when you change screens. Personally I'm using ver 1.01 and VGA, so I'm screwed both ways... ;-) j |%|John Lawitzke, Dale Computer Corp., R&D |%|UUCP: uunet!frith!dale1!jhl Work |%| uunet!frith!dale1!ipecac!jhl Home Inquiring minds just wondering. |%|Internet: jhl@frith.egr.msu.edu [35.8.8.108]

According to my docs, vpix dosent run in the background multiscreen
if you have VGA. This is what I find on my system , SCO Unix 3.2,
Vpix 1.1 with update A.
I also dont remember anything about update A allowing the option
of running multiscreen vpix sessions on inactive screen ??
How do you turn this option on, just in case it may work?

Personally I'm using ver > 1.01 and VGA, so I'm screwed both ways... ;-) I use Simul-Task 2.0 (which is VPIX 1.01 modifed by ATT) on a Vega VGA and don't see this problem. I used Telix (a dos comm program) and downloaded files, with turboc compiling a program in another dos window, and a couple of unix apps running in other virtual terminals and flip back and forth between them. The two problems I have noticed are some dos programs like to switch to some screen mode that blanks the the screen. And when I use the 50 line mode in VGA my cursor disappears. Anyone know with this screen mode switch that's causeing this? Or a tsr that I can use to get it back. I know the program is still running in the background because I can use the keyboard and blindly exit the program. ---Bob -- Bob Palowoda packbell!indetech!palowoda *Home of Fiver BBS* login: bbs Home {sun|dasiy}!ys2!fiver!palowoda (415)-623-8809 1200/2400 Work {sun|pyramid|decwrl}!megatest!palowoda (415)-623-8806 2400/9600/19200 TB Voice: (415)-623-7495 Public access UNIX XBBS

In the newest release of VP/ix you CAN run VP/ix in the backgroud (I.E in a multiscreen) without it halting. The only stipulation is that you need to be running CGA or MONO. -- Michael R.
