Exchange of environmental health information between microcomputers

Programs have been developed which permit the transfer of disk files (programs or data) from a TRS-80, Model-III microcomputer to a TRS-80, Model-I system via an RS-232-C serial interface. The programs allow researchers to effectively use both computers in the entry and processing of air pollution and epidemiological data, in addition to facilitating the exchange of programs, data, and word processor documents between users of the two machines. A detailed explanation is given of how the programs control the RS-232 hardware and use several of the file management routines in each computer's operating system to achieve successful information transfer.
