Don´t Dosbox support game-specific command line input parameters?? For example, the game Sopwith has a command line option (-s) that enables sound before you enter the game. So the command line looks like this:

c:\> sopwith -s

By running it directly from the dos prompt screen opened by Dosbox, it works fine but when you try to execute this same line through a front-end or a batch file for example, it doesn´t work.
