ISORE(8C)

NAME
isore - help out ISODE TSAP programs

SYNOPSIS
isore magic arguments
(under a program loaded with -ltsap)

DESCRIPTION
The isore program is used to correct a deficiency in the 4.2 Berkeley UNIX implementation of TCP/IP. In short, the SIGIO signal for asynchronous notification of socket activity is not implemented. If a transport-descriptor is marked as being asynchronous (the TSAP-provider can initiate INDICATION events at any time), then this capability is necessary. The isore program is spawned automatically when one or more transport-descriptors are marked for asynchronous INDICATIONs. It monitors the TCP/IP traffic, as efficiently as possible, and sends the SIGEMT signal to the program when the network would generate an N-DATA.INDICATION event. The program catches this signal and performs the appropriate action.

This program is mostly likely obsolete on 4.3BSD and SVR3 systems.
