Status-Session

The Status-Session message provides the application with information on changes in the state of a session between the local node and the host. It flows from the node to the application and is used with both SSCP and PLU connections.

See Status-Session Message for further details.

srcl

Source locality.

srcp

Remarks

• The Status-Session message consists of a buffer header only; there is no buffer element.
• The session codes are listed in Status-Session Codes.
• The SNA Server OS/2 and MS-DOS-based 3270 emulators display a session status identifier (–+z_nnn), where nnn is obtained by adding 484 to the value of sessqual from this message.
