Abstract: Examples are disclosed for transmitting a command to control a peripheral device through an audio port. In some examples, the peripheral device may be coupled to a computing device via an interconnect. The interconnect may have an audio jack to couple with the computing device through an audio port and a connector to couple with a serial interface at the peripheral device. For these examples, elements of the computing device may receive a command to control the peripheral device and may generate analog signals including the command and a clock signal. The analog signals may then be transmitted through the audio port. The interconnect may be capable of converting the analog signals to a digital signal that includes the command and clock signal then provide the digital signal to the serial interface at the peripheral device. Other examples are described and claimed.
