UART I/O Control Functions [Serial communication devices.] Collaboration diagram for UART I/O Control Functions: Detailed Description UART _ioctl() commands. These commands are used to control and retrieve hardware specific configurations. The definitions are kept independent from the underlying hardware, but not all commands may be fully implemented in each UART driver. The _ioctl() function expects three parameters: A device descriptor. A command code, any of the UART_... commands listed below. A pointer to a configuration parameter, in most cases an unsigned long.
