Abstract
A system for extending a communications link between a host computer and peripheral device provides true emulation of the peripheral data storage device. The system includes a host extender for communicating directly with the host computer and a peripheral extender for communicating directly with the peripheral device. The host attached and peripheral extenders communicate across the extended communications link. The host extender initially transmits a channel program to the peripheral extender. The system uses the channel program to obtain format information of a particular track of the peripheral device. The host extender stores this format information and uses it to emulate the peripheral device to the host computer.
