3-121 Loss of Workstation EGA or VGA Graphics Display
APPLIES TO: NetWare 3270 Workstation
SUPERSEDES: 3-101
DATE: September 17, 1990
PROBLEM
DOS applications using EGA or VGA graphics do not have screens restored after returning from a
host session.
DISCUSSION
Novell's 3270 emulation software does not currently save and restore EGA or VGA graphic screens.
The NetWare 3270 emulation customization option to save up to 4 "screen pages" of 4K each is only
for text and CGA graphics.
WORK AROUND
Most applications have a way to work around this problem.
For instance, with one version of Lotus 123, it is possible to restore the screen by using the following
procedure: At the blank Lotus screen key the slash character. A menu displays. From this menu the
select worksheet window display option 2. This returns the Lotus display screen to normal.
Lotus 123 Version 3 employs graphics mode rather than text mode, and requires more screen buffer
memory to store the graphic data than is available via the NetWare 3270 emulation software.
