The version of the Telnet/iX Server released with MPE/iX Release 5.5 had several functionality restrictions that were documented in the MPE/iX 5.5 Communicator article, "Telnet/iX Server Functionality Details." The Telnet/iX Server included with this MPE/iX release is now fully functional. The purpose of this article is to update the information from the MPE/iX 5.5 Communicator.

Changes from the MPE/iX 5.5 Telnet/iX Version

  • FControl and FDeviceControl behavior for this version will function as documented in the Asynchronous Serial Communications Programmer's Reference Manual.

    • All Block Modes and Binary Mode are now supported.

    • Type-ahead is now supported.

  • The maximum number of concurrent Telnet Sessions has been raised from 250 to 2000.

  • The TLNETDOC.ARPA.SYS file has been updated with information for the Telnet/iX Server, and is included in this patch.

  • The Telnet/iX Server now supports all of the Telnet commands that require interaction with the Server.

    In addition to the commands open, send break, send AYT, send IP, send EC, send EL, quit, and close that were supported with the MPE/iX 5.5 version, this version of the Telnet/iX Server also supports the toggle and mode commands.

    You should be aware of the following points when using the toggle and mode options:

    • toggle

      The Server was written to assume the user is always right. This means that if you do a toggle echo to allow the client to do all the echoing, the Server stops echoing and leaves all echoing to the client. However, if you then run an application on the HP 3000 that enables echoing, there will be a double echo on your display.

    • mode

      1. Line mode for the HP 3000 server was implemented to be consistent with the HPUX 9.0 Telnet product. Neither of these line modes comply with the RFC-1116 line mode standard.

      2. We recommend that you do not use line mode when running block mode applications on the HP 3000. This may cause the applications to operate poorly.
