One additional note about Wengier's start.exe and XyWrite:If you rename start.exe to command.com, and put it and cmds.list in the OTVDM directory (the same directory that has otvdm.ini, etc.), then you do NOT need to make any change to otvdm.ini in order to Go to DOS or run DOS commands from XyWin. XyWin finds command.com automatically. This makes everything easier to manage.
