12: .in +.5i
13: .ti -.5i
14: .B \*(SDisore
15: \fImagic\0arguments\fR
16: .in -.5i
17: (under a program loaded with \fB\-ltsap\fR)
18: .SH DESCRIPTION
19: The \fIisore\fR program is used to correct a deficiency in the 4.2
20: Berkeley UNIX implementation of TCP/IP.
21: In short,
22: the SIGIO signal for asynchronous notification of socket activity is not
23: implemented.
24: If a transport\-descriptor is marked as being asynchronous
25: (the TSAP-provider can initiate INDICATION events at any time),
26: then this capability is necessary.
27: The \fIisore\fR program is spawned automatically when one or more
28: transport\-descriptors are marked for asynchronous INDICATIONs.
29: It monitors the TCP/IP traffic, as efficiently as possible,
30: and sends the SIGEMT signal to the program when the network would generate
31: an N\-DATA.INDICATION event.
32: The program catches this signal and performs the appropriate action.
33: .PP
34: This program is mostly likely obsolete on 4.3BSD and SVR3 systems.
