Using NS3000/XL Network Services

Differences Between NS3000/V and NS3000/XL 

NS3000/XL is a compatible subset of NS3000/V, the powerful networking
software available on the MPE V/E based members of the HP 3000 family.

However, when communicating between an MPE XL based node an MPE V based
node, if echo ever gets turned off, proceed as follows:

   1.  Issue a colon (:)  to return to your local node.

   2.  Restore the echo on your local system according to the method for
       that node (the method is different depending on whether your
       physical terminal is connected to an MPE V based node or an MPE XL
       based node).  Remember:  the node that your physical terminal is
       connected to always determines how you restore your terminal's
       echo.

   3.  Note that this procedure restores echo on the  local system.  To
       ensure that echo is also restored on the  remote system, you may
       wish to run a program that issues an  FCONTROL 12 on the remote
       system.

Missing Features 

The following list specifies the features that were available in NS3000/V
but are not available in NS3000/XL:

 *  Program-to-Program communication (PTOP) is not available.  For
    information on translating your PTOP applications so that they can
    run on an MPE XL based machine, please refer to the "Conversion
    Checklist" section below.

 *  No-wait I/O Remote File Access is not available.

Changed Features 

The features that changed from NS3000/V to NS3000/XL are as follows:

 *  When using Network File Transfer (NFT) or Remote File Access (RFA) in
    NS3000/XL, only files with MPE V characteristics are supported.  For
    instance, the mapped access file system feature of MPE XL is not
    supported by NFT and RFA in NS3000/XL.

 *  Remote Data Base Access in NS3000/XL is supported only for TurboIMAGE
    databases.  Remember that an IMAGE database on a DS/3000 node can be
    accessed by using an intermediate NS3000/V node.  The  SHOWCOM
    command has been replaced by the  LINKCONTROL STATUS command.
