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 \fIisore\fR 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. .PP This program is mostly likely obsolete on 4.3BSD and SVR3 systems. .SH FILES .nf .ta \w'\*(EDisoservices 'u None .re .fi .SH "SEE ALSO" libtsap(3n) .SH AUTHOR Marshall T.
