A method is described to permit the IBM Token-Ring Network to correctly emulate the NETBIOS interface used by the IBM PC Network hardware. Release 1 of the IBM PC 3270 Emulation Program was originally written to run on the IBM PC Network using the published NETBIOS interface. The Token-Ring Network claims to emulate the same NETBIOS interface. This interface specifies that when a fatal error occurs on the network, the application program (e.g., the IBM PC 3270 Emulation Program) is notified of the error via an appropriate return code. On the Token-Ring Network, however, several seconds will elapse between the time a NETBIOS command is issued and a fatal return code is received, during which time any other commands issued will be placed in a queue.
