ocr: Once you are at a DOS level, you start DSZ by typing in the appropriate command line at the dos prompt, and you will be up and ruming. This is an example of a DSZ command line: DSZ CON port 2 speed 2400 pa7300 pu9 Z pt92 p11200 r In order to insure consistency, and eliminate typo's, it is best to use a Batch file for calling DSZ. Then at the Dos prompt, the only thing you need to type is the name of the batch file.
