Hi all,
Sorry to be asking questions about SYSV386, but I have run out of ideas and decided to give this list a try.
I have a problem that I hope somebody can help me with. The organization that I work for has decided to upgrade the hardware platform for a training device that we support. The purpose of the device is to simulate a radar / sonar display unit. The current hardware is an Intel manufactured 386 25Mhz computer with a PixelWorks CGA video card. All of this wonderful hardware is run by AT&T System V386 Release 3 with a realtime extension package.
Due to portability problems, my company wants to upgrade the hardware platform to a Pentium 100 Mhz ATX motherboard while keeping the video card and OS a constant. We have actually prototyped the system and the OS as well as the simulation software works fine with one small problem. The PnP bios sees the PixelWorks video card as capable of only 40 column mode ( the video card has run in 80 column mode with older Pentium mothers) and as a result henders basic system administration and file editing. The radar / sonar simulation is not affected because the simulation software makes function calls to a PixelWorks library and does not use video bios calls.
Here comes the million dollar question. Is there any way to reset the console to 80 column mode short of flashing the bios with an up or down grade? The stty command is present in the SV386 but does not support column or row arguments. Also there is no way to disable the PnP mode from the bios or manually specify the video mode. Any help is greatly appreciated. Thanks in advance.
