Data Interchange between Systems having Different Media Sizes

A universal synchronous/asynchronous receiver/transmitter (USART) is used to connect a general purpose computer having one storage media size to another workstation having a different media size so that data may be exchanged between the systems having incompatible media.

In the figure a primary workstation, such as a word processing system, having a high quality printer utilizes a SIZE 1 diskette. It may be desirable to connect this primary workstation to a general purpose computer having a disk storage of a different size so that data resident in the general purpose computer or on its SIZE 2 disks may be further processed and printed by the high quality printer of the primary workstation. Since the SIZE 2 disk of the general purpose computer cannot be read by the reader of the SIZE 1 disk of the primary workstation, a low-cost communications link between the systems is desirable. The USART adapter card and USART are added to the general purpose computer to communicate, via a twisted pair of wires, with the primary workstation. The twisted pair is connected to the primary workstation at a printer sharing card (PSC) at the primary workstation.

Software is provided in the form of a "remote copy task" in the work diskette task at both the primary workstation and the general purpose computer. However, this software is considerably less complex than conventional communication software. The function of this...
