The online docs *show* the parameter contents. If you open the Control Program online manual, go to the "Generic IOCtl Commands" section. Click on the + to expand it and then on the + left to the "Category 1 ASYNC". Then move to "Function 53H - Set DCB", double click on it. Two windows appear, double click on "Parameter Packet" in the left window and you are told how the structure pointed to by the parameter pointer must be set up ... Although the online DOCS don't mention it, there are predefined structures for the parameter blocks in BSEDEV.H.
