Abstract

A system and method for connecting a hardware emulation of an electronic device to a computer peripheral that includes a computer for receiving data from the peripheral and storing the received data in a first buffer. The computer next transmits the received data to the emulation at a slower speed. The computer also receives data from the hardware emulation and stores the received data in a second buffer. The computer then transmits the data received from the hardware emulation to the peripheral.
