Unsolicited Messages

An unsolicited message is an output message not associated with an input message. An unsolicited message results from a host application sending an unsolicited message. TPF SNA supports a ZSNDU interface only for SNA resources in session with a non-SNA application (that is, addressing via LNIATA/LEID rather than RID).

Unsolicited Messages Destined for a LNIATA/LEID

For an unsolicited message destined for a LNIATA/LEID, TPF notifies the terminal of the pending unsolicited message. The operator must request delivery of the message. Unsolicited messages are non-recoverable.

Unsolicited Messages Destined for a RID

An unsolicited message destined for a RID is treated as a normal data message. The operator cannot request delivery of the message. Unsolicited messages are non-recoverable.
