Simh problem - test-drb@ccmp.vtda.org

...
  After a little searching, I found that Windows
doesn't install the
 ANSI.SYS driver when it is installed, and without this, DOS cannot
 interpret the ESC codes.  
Just FYI: 
This will work on Win9x but not on Windows 2000 or XP (or Vista).
On the NT product line, ANSI.SYS works in the MS-DOS emulation 
subsystem only, and doesn't work for 32-bit console applications.
So, if you install simh on Windows 2000 or XP, you'll need to use
a telnet application.
