LUA Verbs

RUI_TERM

This verb ends the SSCP session for an LUA application. It also brings down the LU session if it is active.

RUI_WRITE

This verb sends data to the host on either the SSCP session or the LU session.

1.4.2 SLI Verb Summary

The following list contains a brief summary of each of the LUA SLI verbs (for a detailed explanation of each verb,

see Chapter 5, SLI Verbs):

SLI_BID

This verb enables the application to determine when information from the host is available to be read.

SLI_CLOSE

This verb ends the session for an LUA application.

SLI_OPEN

This verb sets up the session for an LUA application.

SLI_PURGE

This verb cancels an outstanding SLI_RECEIVE verb.

SLI_RECEIVE

This verb receives data or status information sent from the host to the LUA application’s LU, on either the

SSCP session or the LU session.

SLI_SEND

This verb sends data to the host on either the SSCP session or the LU session.

On the SLI_OPEN verb, the application can optionally specify the addresses of its own routines to process BIND,

STSN, and SDT requests from the host. If it provides these routines, and a request of the appropriate type arrives

from the host, LUA sends an additional verb to the appropriate application-supplied routine to allow it to process

the request, as follows.

SLI_BIND_ROUTINE

LUA sends this verb to the application-supplied BIND routine when a BIND request arrives from the host.

The application can accept the BIND, negotiate BIND parameters, or reject the BIND as described in Section

2.4, SNA Information.

If the application does not provide a BIND routine, LUA performs limited BIND checking and responds to

the host appropriately.

SLI_STSN_ROUTINE

LUA sends this verb to the application-supplied STSN routine when an STSN request arrives from the host.

The application can respond to the STSN or reject it with an appropriate SNA sense code, as described in

Section 2.4, SNA Information.

If the application does not provide an STSN routine, LUA returns a positive response indicating that no data

is available.

SLI_SDT_ROUTINE

LUA sends this verb to the application-supplied SDT routine when an SDT request arrives from the host. The

application can respond to the SDT or reject it with an appropriate SNA sense code, as described in Section

2.4, SNA Information.
