 USRobotics (USR) introduced a similar system, known as "HST", although this supplied only 9,600 bit/s (in the early versions) and provided for a larger backchannel.Rather than offer spoofing, USR instead created a large market among FidoNet users by offering its modems to BBS sysops at a much lower price, resulting in sales to end users who wanted faster file transfers.Hayes was forced to compete, and introduced its own 9,600 bit/s standard, "Express 96" (also known as "Ping-Pong"), which was generally similar to Telebit's PEP.
