Abstract
A method, system and article of manufacture for determining whether a presentation space (PS) is completely built in a TN3270 environment. In general, a TN3270 client is provided with an indication from a TN3270 server that a Systems Network Architecture (SNA) application has completely built the PS. In some cases, the indication prompts the TN3270 client to unlock a device, such as a keyboard.
Claims29
A method, comprising:
- sending, from a TN3270 server to a TN3270 client, a command which unambiguously indicates to the TN3270 client that a Systems Network Architecture (SNA) application has completed building a presentation space in the TN3270 client.
In an environment comprising a (i) primary logical unit (PLU) comprising a Systems Network Architecture (SNA) host application, (ii) a secondary logical unit (SLU) and (iii) a SNA network connecting the PLU and SLU, a method, comprising:
- sending, from a TN3270 server of the SLU to a TN3270 client of the SLU, a command which unambiguously indicates to the TN3270 client that the SNA host application has completed building a presentation space of the T3270 client.
A secondary logical unit connected to a primary logical unit (PLU) via a Systems Network Architecture (SNA) network, comprising:
- a TN3270 server configured to send a command;
- and
- a TN3270 client configured to receive the command, wherein the command unambiguously indicates to the TN3270 client that a SNA host application of the PLU has finished building a presentation space of the TN3270 client.
A system, comprising:
- a primary logical unit (PLU) comprising a Systems Network Architecture (SNA) host application;
- a secondary logical unit (SLU) connected to the PLU by a SNA network, the SLU comprising:
- a TN3270 server configured to send a write command;
- a TN3270 client configured to receive the write command, wherein the write command unambiguously indicates to the TN3270 client that the SNA host application has completed building a presentation space of the TN3270 client;
- and
- a telnet network connecting the TN3270 server and the TN3270 client.
A method, comprising:
- sending a command from a TN3270 server to a TN3270 client when the TN3270 server receives a signal from a Systems Network Architecture (SNA) application demanding ownership of a presentation space of the TN3270 client.
