Multi-mode interfaces having secure alternate modes are disclosed. An example method includes exposing to a device, during a first alternate mode negotiation session, an availability of a first secure alternate mode on a host, authenticating the device to the host using the first secure alternate mode, and responsive to the device being authenticated, exposing to the device a second secure alternate mode.

Input/Output port configurations using multiplexers are described herein. An example computing system includes a multiplexer having a first input, a second input, and an output. The computing system also includes a first channel connecting the first input to a first host controller, the first host controller to transfer data at a first speed, and a second channel connecting the second input to a second host controller, the second host controller to transfer data at a second speed higher than the first speed. The example computing system further includes a third channel connecting the output to a port, the port to receive a connector of an electronic device, and a line selector to, based on a type of the electronic device connected to the port, configure the multiplexer to electrically couple the output to the first input or the second input.

Styli for generating alert notifications to prevent unintentional marking of interactive devices are disclosed. A disclosed stylus includes a housing and a processor. The housing is to interchangeably receive a physically marking nib and an electronic marking nib. The processor is carried by the housing. The processor is to determine a received nib is the physically marking nib. The processor is further to determine a distance between the stylus and an interactive device satisfies a threshold. The processor is further to generate an alert notification based on the received nib being the physically marking nib and the distance between the stylus and the interactive device satisfying the threshold.
