Recently I had to bring up a library system (running under dos) on a Sun Roadrunner. I had no problem running it under Sunview/Dos Windows, but when trying to run the same applications on a tty with dos -w (dos without windows), the dos shell came to a halt, without producing a single char of output. The application (bought, no source) starts in the usual PC manner, creating a nice double box around some text, offering a choice. It uses NO graphics (other than graphic chars) or special boards/mouses or other woodoo. And, again it runs without problems under sunview (double boxes an' all). So my question is: Does anyone have a clue to whether I have a chance in running from an ordinary terminal, or I have to move the goddam console & chassis to our library and teach our librarian about sunview. Not to mention I would have a big problem in putting it on a network there. Other UNIX/dos emulations I have heard of, such as Vp/IX, can map graphics char to a approximation on a tty. Sun does not mention neither restrictions nor features when running dos on a tty. Clues or information anyone ? Lars Povlsen, Comp. Science Departement, University of Copenhagen Denmark

Can ANYONE explain why VP/ix on the 386i (a.k.a. DOSWindows) is crippled
regarding remote DOS execution (none on serial terminals, stdin/stdout
only on network nodes), when SCO and others supply it with serial terminal
execution enabled AND screen mapping too ? I've heard rumours, but let's
hear some facts.
A full screen-mapped ( MDA anyway) serial port and network DOS capability
would be highly desirable. Are you listening, SUN ?

Because the application uses the separate VGA monitor as its "dos window", you'd think having a window pop-up on the 386i's display would be unnecessary. But, to focus keyboard input using the mouse, it is necessary to have a region to point to. It would be nice if it could be just a sunview window running dos -w, possibly in the background. [Note that our VGA application doesn't use the keyboard for input, but instead, uses a serial port driven by a touch screen sensor, which is sampled even when the dos window is iconic and off screen]. So we tried dos -w to invoke the application, and got the message: "can't untrack memory, permission denied." According to Sun, dos -w will support dos applications that use only bios interrupts 10 (VIDEO_IO) and 16 (KEYBOARD_IO) for talking to the keyboard and display. If (since) your application uses something else, in addition to these, the invocation of other interrupts seem to have hidden results. Unfortunately, such deviant behavior isn't reported in any log file either, so it's hard to know what's going on. I think they are considering to, at least, report having trapped an invalid bios interrupt when running the dos -w. I'd also be careful trying to run dos -w from a terminal. Depending on which vendor's serial card and driver you are using, the dos support seems to vary quite a bit. Hope this helps. Misery loves company.
