Video mode/palette corruption????

Video mode/palette corruption????

Video mode/palette corruption????

(OP)
Hello,
Could anybody help me?
I need help because I have a strange problem ...
At my work I have a DOS application written in Clipper which use ccMail call thru a bat file. Everything is OK on color display. But on monochrome display (Digital DEC Pos 2 workstation, with NeoMagic MagicGraph 2070 128K SVGA video card) doesn't work well. After ccMail call and return in CLipper application some of the frames is not showing anymore. And even more, any frame generate after is not show well. Clipper app works on text mode (video mode 3 80x25).
I test video mode before and after call ccMail ( 03 before and 07 after), and I try to restore it at 03, but no change appears.
I tried to save screen (from B800:0000 address) before ccMail call and to restore after but is not working.
I have no idea what can I do.
Can anybody help me?
Can be this problem because the ccMail is calling within a .bat? Or is color palette corupted?

Any suggestion is wellcome.

Thank you ,
Alice

RE: Video mode/palette corruption????

Hello,

Mode 3 is color text mode, mode 7 is mono text mode. So you want to leave it at that. Also, the mono text screen is at B000:0000 not at B800:0000
