Try this ... It seems to work on Win2K for old Dos stuff:
Create a batch file (i.e.-> myapp.bat) with 'Notepad' to set the consol mode and to launch your app with the following commands:
mode con: cols=80 lines=26
C:\<full Path Name>\<Application executable filename>
Then create a pif file (shortcut file). On the "program" tab in the 'cmd line' box, enter the full path to the batch file location you just created above. In the 'Working:' box enter the full path to the actual folder of your application executable. In the "Run" box select "normal window". Check the box "close on exit". On the "Screen" tab, select "Window" in the "usage" frame and check all the check boxes.
Start the whole business up by launching the new pif file (shortcut) you just created.
When it starts up, press the <alt><enter> keys to toggle the screen size.
It seems long and arduous but the trouble is worth it if you still run the old stuff!
