- What video card are you guys using?
-
- My brothers machine (25MHz 386 8MB) had problems doing 9600 baud downloads
- with an ATI VGA Wonder+. When he moved the mouse a lot or did a lot of
- disk operations, packets would be lost. (using TE/2, zmodem)
-
- But after I bought him an ATI Graphics Ultra for his birthday those problems
- went away. I'm not saying its the VGA Wonder's fault but that possibly the
- video overhead caused the problem. This was before I bought him an I/O card
- with a NS16550AFN on it.
