Is it possible? Os/2 comes with the capability of having a "DOS Compatibility Box" in which you can run a single dos session. You can run multiple OS/2 tasks in the background when you have the DOS session in the foreground, but MS-windows-like, it will suspend the DOS session to put an OS/2 task in the foreground. If you want true multitasking of DOS applications (or background execution of DOS applications) you really need a '386 and either Desqview or windows-386. -- john nelson UUCP: {decvax,mit-eddie}!genrad!jpn smail: jpn@genrad.com ------------------------------------------- From dmurdoch@watstat.waterloo.edu Tue Jun 20 05:50:25 1989 Received: from Lanai.CS.UCLA.EDU by maui.cs.ucla.edu (Sendmail 5.61.ucla-33/2.17) id AA16153; Tue, 20 Jun 89 05:50:24 -0700 Received: from watstat.waterloo.edu by lanai.cs.ucla.edu (Sendmail 5.61.ucla-33/2.17) id AA20139; Tue, 20 Jun 89 05:50:17 -0700 Received: by watstat.waterloo.edu for gblee@CS.UCLA.EDU id <AA06307>; Tue, 20 Jun 89 08:49:20 EDT Date: Tue, 20 Jun 89 08:49:20 EDT From: Duncan Murdoch <dmurdoch@watstat.waterloo.edu> Message-Id: <8906201249.AA06307@watstat.waterloo.edu> To: gblee@CS.UCLA.EDU Subject: Re: x-window on dos or os/2 Newsgroups: comp.sys.ibm.pc,comp.graphics,comp.dcom.lans In-Reply-To: <25024@shemp.CS.UCLA.EDU> Organization: U. of Waterloo, Ontario Cc: Status: RO In article <25024@shemp.CS.UCLA.EDU> you write: >Hi! folks! >Does anybody know any X-window or similar powerful window software >which is runing on Dos or Os/2? Any pointer will be appreciated. I was told a few days ago that IBM, as a postscript to an announcement about their X-windows implementation for their new Unix (POSIX? A/IX? I forget the name they use), mentioned that they're also releasing a DOS version. I didn't get any more detail than that; I don't know who you'd contact to find out.

In this sense, x and Presentation Manager are quite similar. You can quite easily open as many simulataneous windows for local tasks as you want, and other windows for remote access if you have a network that runs under OS/2. > In Os/2, can we run several jobs at the same time, background and forground? I do it all the time. As long as the jobs you are running are so-called "protected mode applications" (i.e., written for OS/2 rather than DOS), you can run as many of them as you want in background and as many as fit on the screen in foreground. The process receiving input always runs at much higher priority than any other, though. > Also, i want to know in PS/2, is there any way to use Dos and Os/2 > at the same time, in other words, open one window for Dos, and > another window for os/2... Is it possible? Any OS/2 machine (PS/2 or not) can run DOS applications at the same time as OS/2 applications. However, there are strong limitations on this: (A) the DOS application always owns the whole screen, so you can't put it in a window; (B) only one DOS application at a time (although many OS/2 applications can be running along with it); (C) DOS applications receive no time when put in background; they only run in foreground; (D) only well- behaved DOS applications are supported. I don't work on a PS/2, so I can't swear to it, but I am reasonably certain that they allow you no special features beyond any other OS/2 machine and, in particular, that you can not place DOS and OS/2 applications in side-by- side windows on one.

Any pointer will be appreciated. >Please e-mail me. Thank you. >--Geunbae Lee, AI-UCLA Here is an old article about xwindows that was posted to the net. The DOS/UNIX integration product "PC-Connect" has been launched in a shrink-wrapped package, and Sphinx Software are handling distribution of the SCO XENIX version in the UK. PC-Connect, developed by the VisionWare division of Systime Computers Limited, has previously been available through OEM channels and is also available for other versions of UNIX/XENIX. PC-Connect allows IBM-compatible PC or PS/2 personal computers running Microsoft Windows to become multi-windowed workstations connected to one or more UNIX host systems. It uses the graphics interface of Windows to provide a homogeneous environment for DOS and UNIX applications. The physical links between the PCs and host systems can be RS232C serial lines, and/or one of the several supported networks including Ethernet with TCP/IP. A Desktop window is displayed on the PC screen, containing icons which show programs available to be run. The icons can represent DOS or UNIX programs. Clicking on an icon with the mouse starts an application, without the user needing to know which computer the program will execute on. If it is a DOS program it runs as a normal Windows application. A UNIX program runs in a window which initially contains a terminal emulator, so that standard UNIX applications can run unchanged. A PC-Connect Development System is available which allows programmers to write UNIX programs which make use of the Microsoft Windows API on an attached PC. A UNIX program can use windows, icons, menus and the mouse to provide a user interface which appears similar to DOS-based Windows applications. A full range of graphics functions is available which effectively provides a graphics terminal in full color for UNIX at a very low cost. Other products in the VisionWare range include: PM-Connect, which is a version of PC-Connect implemented to work under the Presentation Manager interface of OS/2. A Microsoft Windows-based X Window System server which allows host- based X clients to use standard X protocols to display information on a PC screen. SQL-Connect, which allows a PC user to make SQL requests of host- based relational database management systems. SQL-Connect runs as a DDE server on a UNIX host system, and any application which uses DDE can pass an SQL request to it. For example, Microsoft Excel running on a workstation can extract data from a corporate database and display the information in a spreadsheet. Initially the RDBMSs supported are Informix and Oracle. A package of programs is being developed which will provide the UNIX system administrator with a friendly Windows interface to commonly used UNIX utility programs. The object is to allow a non-technical system administrator to operate and manage a UNIX system without ever leaving the Microsoft Windows environment.

No. When the DOS Compatibility Box is brought to the foreground, all OS/2 programs are suspended. This is because the DOS program must execute in real mode, while OS/2 programs use protected mode. This eliminates the possibility of multitasking mixed DOS and OS/2 programs. 386 machines can multitask DOS applications by using the 'virtual 8086' mode of the 386 processor. However, you cannot run OS/2 programs in this environment. >-- > john nelson > Don Pajerek

With the DOS box in the foreground, the OS/2 sessions WILL continue in the background, albiet somewhat more slowly. When the DOS box goes in to the background, the DOS program stops, though.
