ocr: DSZ command lines can be as simple or complex as you choose to make them. This example shows a command line that operates with default parameter settings and without options. DSZ port 2 speed 2400 r In theory, it would be possible to operate without designating the port, or the speed. DSZ, has a default of port 1, and the current operating speed. However, because of differing program operation, does not always sense those defaults. As a result, I make it a practice to enter the values anyway.
