In an earlier posting, I reported some difficulties with dvivga, demacs
and ansi.sys. on an 80386 MSDOS system. I thought that dvivga was incompatible
with ansi.sys, the latter being necessary for me to run demacs.

Since my earlier posting, I have made some progress. I reinstalled
ANSI.SYS or TANSI.SYS and rebooted. Then I went directly into dvivga
and it worked fine. Therefore, DVIVGA IS NOT INCOMPATIBLE WITH ANSI.SYS
or TANSI.SYS.

Then I used demacs to edit a TeX file. It let me edit the file but gave
me an error message, as it always does, because I don't have the .el file
for TeX. Then I exited demacs. I should mention that I have commented out
everything in the _emacs file for demacs.

After exiting demacs, I tried again to look at the dvi file with dvivga
and this time the problem returned: the numeric keypad and the arrow
keys did not work properly. Therefore, DVIVGA IS INCOMPATIBLE WITH
DEMACS.

In other words, running demacs seems to change something from the way
ansi.sys had it to something else that is incompatible with the way
dvivga uses the keypad and arrow keys.

Any insights into this mess will be welcome.
