A method is described which allocates fewer buffers to a communication buffer pool and while maintaining existing performance levels. The IBM PC 3270 Emulation Program is a software package which allows IBM Personal Computers to emulate IBM 3270 family of devices. Functions emulated include a subset of 3274 51C control unit, 3278 display station, and 3287 printer. Four configurations are possible. Except for the stand-alone configuration, the IBM PC Network hardware or Token Ring is also required for data distribution. In these configurations, one of the PCs on the network is designated as the "Gateway." A "Gateway" acts as a concentrator/distributor. On the one hand, "Gateway" communicates to the host either through a SDLC (Synchronous Data Link Control) or a TCA (Telecommunications Access) link.
