In order to reproduce, call make term and something like ps; help. This sends ps and help back to back to the node. Theoretically the node should respond with the output of ps followed directly by the output of help, but will only do the first one. Verified on IoT-LAB_M3 and pba-d-01-kw2x with default and ng_networking example.

Not tested on ARM7 or MSP430 platforms.
