A method is described to permit a "Gateway" and a Network Station on the IBM PC Network to accurately maintain the IBM PC Network session status. IBM PC Network SNA 3270 Emulation Program is a program product that provides 3720 emulation for Personal Computers (PCs) connected together on the IBM PC Network. One PC acts as a "Gateway" to the host computer through an SNA/SDLC communications link. Other PCs, called Network Stations, are logically connected to the "Gateway" PC through IBM PC Network sessions. The "Gateway" and the Network Station, among other things, maintain the IBM PC Network status of their logical connections on the Network. For example, if a Network Station powers off or ends the Communications Task, the logical connection becomes inactive and the "Gateway" is informed of this.
