Abstract

A method is described to provide the IBM Personal Computer (PC) Network SNA 3270 Emulation Program product with the ability to format a printed output printing on an IBM PC printer as instructed by the SNA Character String (SCS) datastream. The IBM PC Network SNA 3270 Emulation Program is a program product which emulates a 3274 control unit with a 3278/3279 display and a 3287 printer. It connects to the host using a Synchronous Data Link Control (SDLC) line control and the Logical Unit Types 1,2 and 3 subset of the IBM System Network Architecture (SNA) protocol. The SCS controls are EBCDIC control codes that define a datastream. Their primary function is to format a visual presentation medium, such as a printed page printing on a 3287 printer.
