dos-shell under w2k

[Martin Siegenthaler]

hi all

when you run old dos-programs under w2k in the dos-window,
then the entered characters from the keyboard are
displayed delayed.
if dos-program runs in fullscreen-mode, all is ok

is there a way to adjust this timing / the keyboard poll
rate ?

thanks

Martin

I get better performance by using COMMAND.COM and then
invoking the program from the Command line.
Don't use CMD.EXE to invoke DOS programs, you need
COMMAND.COM which will preload the NTVD 16-bit sub system.
There's not much you can do about the keyboard polling
rates. When the command line is in Windowed mode it
recieves less timeslice quanta then when it is in
Fullscreen. You can adjust the Priority rate from the
Task Manager for NTVDM.EXE but take caution: making this
setting 'RealTime' will deadlock the computer if the DOS
application crashes or you attempt to minimize the window.
