APPC Option Set Support

The following option sets are supported:

Conversations between programs located at the same LU

Allows a program to allocate a conversation where the remote program is in the same LU as the local program.

Delayed allocation of a session

Allows a program to allocate a conversation and begin sending data before a session can be assigned to support the conversation.

Immediate allocation of a session

Allows a program to allocate a contention-winner session only if one is immediately available, otherwise the allocation fails.

Session-level LU-LU verification

Provides LU security by designating a password to verify the identity of a remote LU.

User ID verification

Allows a program to allocate a conversation with user verification by means of a supplied password or an already-verified indicator where appropriate.

PIP data

Allows a program to allocate a conversation and supply program initialization parameters to the attached remote program.

Logging of data in a system log

Allows a program to record error information in a system log.

Flush the LU's send buffer

Allows a program to explicitly cause data transmission on a session.

Prepare to receive

Allows a program to change from send to receive state with a number of different options.

Receipt with wait

Allows a program to operate a number of conversations and be notified when information is available on any one of them.

Receive immediate

Allows a program to request any data on a conversation but continue processing if none is available.

Test for request-to-send received

Allows a program to test whether a request to send indication has been received on a conversation.

Data mapping

Allows a program to request the mapping of data by the local and remote LUs.

Get attributes

Allows a program to obtain information about a mapped conversation.
