Many devices may comprise interfaces, such as serial interfaces, over which configuration and/or enablement/disablement of device features may be provided to the device. Connecting a computer to individual devices for manual configuration may be cumbersome and/or time consuming. Accordingly, as provided herein, a device interfacing component (e.g., a microcontroller integrated into an interface cable) is configured to couple to a target device. The device interfacing component may receive data streams from the target device, and may match strings, within the data streams, to expressions. If a string matches an expression (e.g., “F5 for IP setup”), then a corresponding scripted response may be executed to send a response instruction (F5, wait 10 seconds, enter key, “192,168.0.1”) to the target device. In this way, the device interfacing component may provide automated configuration for the target device and/or may be daisy chained with other device interfacing components for configuration of other target devices.
