The PUMP command is used to switch on/off the peristaltic pump at
the 838 Advanced Sample Processor. The PERISTALT command
switches on or off the peristaltic pump, according to the current
state. Pump rate and rotation direction of the pump drive can be set
in 15 steps. A negative value of the pump rate defines a counter-
clockwise rotation. A positive value of the pump rate defines a
clockwise rotation.
