Several IBM RS/6000 models have two processors, a primary CPU and a service processor. When the system is powered down, but still plugged in, the service processor remains active. An IBM3151 terminal can be plugged into this processor via serial cable and used to manage the system.

TinyTERM plugged into the same port does not work until the RS/6000 is booted. At that point, TinyTERM works correctly.
