Abstract: A data communication system for allowing communication between various devices and various operating systems across various types of networking systems. The data communication system includes an host computer system 10 with a display device 15 and a processor 17 for generating signals for the display device, at least one peripheral device 56, and a dynamic device driver 42 for allowing two-way communication between the peripheral device and the host computer system. The dynamic device driver includes an operating system specific portion 33, configured for the operating system of the host computer system, and an operating system independent device driver portion 34, configured for the peripheral device. The operating system includes a linking mechanism 19 for allowing two-way communication between the operating system specific portion and the operating system independent device driver portion, thus allowing two-way communication between the processor and the peripheral device.
