Serial Driver Routines

You can use the Serial Driver routines to

This section describes the control and status routines unique to the Serial Driver, as well the convenience routines for accessing them. Other Serial Driver functions, such as reading and writing, are accessed through the Device Manager. For information about the Device Manager functions for opening, closing, and communicating with device drivers, see the chapter "Device Manager" in this book.

The Serial Driver convenience routines described in this section are always executed synchronously when called using the high-level interface. To execute these functions asynchronously you must use the equivalent low-level Device Manager control or status call (PBControlAsync or PBStatusAsync). The csCode value for each routine is listed in the assembly-language information section of the routine description.
