Abstract

This memo describes the interface to the IBM 5250 Telnet server that allows client Telnet to request a Telnet terminal or printer session using a specific device name. If a requested device name is not available, a method to retry the request using a new device name is described. Methods to request specific Telnet session settings and auto-signon function are also described.

Abstract

   This memo describes the interface to the IBM 5250 Telnet server that
   allows client Telnet to request a Telnet terminal or printer session
   using a specific device name.  If a requested device name is not
   available, a method to retry the request using a new device name is
   described.  Methods to request specific Telnet session settings and
   auto-signon function are also described.

   By allowing a Telnet client to select the device name, the 5250
   Telnet server opens the door for applications to set and/or extract
   useful information about the Telnet client.  Some possibilities are
   1) selecting a customized device name associated with a particular
   user profile name for National Language Support or subsystem routing,
   2) connecting PC and network printers as clients and 3) auto-signon
   using clear-text or DES-encrypted password exchange.

   Applications may need to use system API's on the AS/400 in order to
   extract Telnet session settings from the device name description.
   Refer to the Retrieve Device Description (QDCRDEVD) API described in
   the AS/400 System API book [3] on how to extract information using
   the DEVD0600 and DEVD1100 templates.

   This memo describes how the IBM 5250 Telnet server supports Work
   Station Function (WSF) printers using 5250 Display Station Pass-
   Through.  A response code is returned by the Telnet server to
   indicate success or failure of the WSF printer session.
