IOCTL_SERIAL_SET_TIMEOUTS IOCTL

Description

The IOCTL_SERIAL_SET_TIMEOUTS request sets the time-out values that the serial controller driver uses for read and write requests.

To get the time-out values, a client can use an IOCTL_SERIAL_GET_TIMEOUTS request.

For more information about time-outs, see Setting Read and Write Time-Outs for a Serial Device.
