TELNET

This section describes both the TELNET client in BS2000 and the TELNET server (as of "TELNET server").

Basic function

When a user sets up a connection to a partner system with the TELNET program, his or her terminal behaves like a line terminal directly connected to the partner system.

TELNET enables interactive communications only in line mode. Consequently, if the partner system is a BS2000 system, for example, FHS and EDOR cannot be used, and SDF and EDT may only be used in line mode. Similarly, if the partner system is a Unix system, for example, CED cannot be used.

Other functions

• Information for the user
  In a TELNET session, the user can obtain information on

  • the available commands and their significance,

  • the partner system with which the user is currently connected and the conditions (options) for data transfer.

• Monitoring functions
  Trace functions corresponding to the server trace functions that can be initiated by the administrator via /INFORM-PROGRAM command of the system console have also been implemented in the client for maintenance and diagnostic purposes.

• Interface to the local and remote operating system
  An interface to the local operating system is provided to allow the user to issue a BS2000 command without having to interrupt the program run (and first clear the connection to the partner system).
