ABSTRACT:
A transmission rate control system is adapted for an information processing system which exchanges data between a host unit and at least one terminal equipment via a first transmission line. The transmission rate control system includes a first part provided in the host unit for generating a clock switching signal which instructs a switching of a first clock signal which determines an operation of the terminal equipment, a second part provided in the terminal equipment for generating the first clock signal which determines the operation of the terminal equipment, a third part provided in the terminal equipment for switching a period of the first clock signal generated from the second part in response to the clock switching signal received from the main unit, so that a transmission rate of the terminal equipment is switched, and a second transmission line provided exclusively for transmitting the clock switching signal from the host unit to the terminal equipment.
