The capabilities of the personal computer are under utilized and limited to terminal emulation and file transfer. For such an environment, a software solution is presented to improve the computing platform between IBM mainframes and personal computers without modifying any existing, intervening communication equipment. Transparent communication support for distributed, interactive applications is provided through the operation of a data link control protocol. The communication services are applied to the development of a distributed WYSIWYG page previewer for SCRIPT/VS.vii, 135 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1992.B427Computer networks -- Communication systemsIBM 3270 (Information display system)Microcomputers -- Programmable peripheral interfacesThesishttp://scholar.lib.vt.edu/theses/available/etd-12162009-020144/
