Chapter 16 - Serial Endpoint Providers / Serial Endpoint Providers Reference

Serial-Specific Commands

Serial endpoints support several serial-specific commands that use the OTIoctl function, which is described in the chapter "Providers" in this book. This function accesses the equivalent low-level serial driver control or status function (PBControlAsync or PBStatusAsync). The csCode value for each routine is listed in each command's description. For information about Device Manager functions for opening, closing, and communicating with device drivers, see the book Inside Macintosh: Devices.
