On September 30, IBM's newest version of TCP/IP for MVS became available.
With IBM's TCP/IP for MVS, you can bring the power and resources of your MVS systems to TCP/IP networking
environments. With TCP/IP for MVS, your MVS systems can act as peers with other hosts in open TCP/IP networks. Your
applications can be shared transparently across MVS, UNIX**, VAX, and other environments. You can also send messages,
transfer files, share printers, and access remote resources across a broad range of systems from diverse vendors.
IBM's TCP/IP for MVS is the first choice for MVS TCP/IP connectivity. Designed to meet the needs of enterprises with
complex networking requirements, TCP/IP for MVS applies IBM's experience in the design and development of large systems
to the implementation of TCP/IP on the mainframe. TCP/IP V3R1 for MVS offers a wide range of client/server applications,
programming interfaces, and connectivity options, plus the data integrity and performance that you've come to expect from
IBM.
OpenEdition MVS integration
Now, TCP/IP for MVS supports OpenEdition* MVS, a set of open, vendor-independent standards incorporated in MVS/ESA
Version 5. With the new OpenEdition MVS Sockets application programming interface (API), you can write applications to an already familiar UNIX-based interface. Your applications can then take advantage of a more efficient cross-memory path.
Application development
With this release of TCP/IP for MVS, you'll receive more application programming interfaces (APIs) to help you develop new
and better applications for network connectivity. New and enhanced APIs include IMS Sockets support, Sockets Extended,
REXX Sockets, and the X/Open Transport Interface (XTI). With TCP/IP for MVS, you can develop applications using well-
known programming languages, like assembler, COBOL, PL/I, and C.
Network Print Facility
TCP/IP for MVS features a new Network Print Facility (NPF), which lets you print data from your MVS system on printers
anywhere in your TCP/IP network. Through the options of NPF, you can choose which printer you want to use and the
processing to be performed. You can also send print output to multiple destinations, retain data sets after processing, and
queue data sets that can't be delivered immediately.
System security
New enhancements to TCP/IP for MVS allow you to control the remote log-in services provided by the Telnet server on the
MVS host. One such enhancement is IP-address-to-LU-name mapping, which lets you tie groups of IP addresses to specific
applications. This means that you can more easily access the applications you use most. It also means that you have more
control in determining who can access which applications.
High-speed file transfer
TCP/IP for MVS now includes both Pascal and C FTP servers, enhancing its file-transfer capabilities. You can resend large
files in less time, use less bandwidth when transferring files, and recover files more easily. Both FTP servers include a
checkpoint/restart function, data compression, tape support, and other new features. Additionally, the C FTP server has
delete/catalog options that automatically handle file-transfer failures, so you don't have to.
Terminal access
If you need to access 3270 mainframe applications from UNIX and other systems, you can do so easily with the Telnet tn3270
support provided by TCP/IP for MVS. Telnet features include full-screen and ASCII line-mode support. TCP/IP for MVS also
gives you Unformatted System Services (USS) Message 10 support, making it more transparent to access 3270 systems
through Telnet if you're accustomed to SNA networks.
LAN and channel interfaces
TCP/IP for MVS provides broad support for LAN and channel attachment interfaces. Supported LAN interfaces include
Ethernet, token ring, PC Network, and FDDI. Channel attachment support includes channel-to-channel (CTC) 3088 support,
High Performance Parallel Interface (HiPPI), ESCON*, HYPERchannel**, and Continuously Executing Transfer Interface
(CETI).
Service and support
IBM provides worldwide service and support for TCP/IP for MVS. IBM's technical support structure is easy to use and offers a variety of services, ranging from base support included with the product to more sophisticated fee services. You can pick the support you need from a portfolio of services, offering various levels of access to IBM experts.

Want a Sneak Preview?
There are three TCP/IP previews available through your IBM account representative on 3.5" HD diskettes. Each interactive
preview provides a high-level marketing overview of its product, contact numbers for service and education, and a glossary of
networking terms. Previews are available at no charge. Currently, the following TCP/IP previews are available:
TCP/IP V2.0 for OS/2
TCP/IP V2.1 for DOS
TCP/IP V3R1 for MVS
Previews are optimized for 486/33 machines and VGA resolution, but will run on 386DX/20+ machines (animated sequences
may be slow). They run under WIN-OS/2 or native Windows 3.1 and require about 3MB of hard disk space. RAM
requirements are those specified as the minimums for the operating systems.
The TCP/IP for OS/2 and DOS previews can be found on the current Networking Systems CD-ROM collection kit (SK2T-
6022). The MVS preview will be included in the next update. For details on this CD-ROM and how to get yours, see "This CD Is Just What I Needed" later in this newsletter.
The new release of OS/2, called Warp, includes a number of TCP/IP applications, which are bundled together as a package
(the IBM Internet Connection for OS/2), and included as part of the Warp Bonus Pak. Using the IBM Internet Connection for OS/2, in conjunction with a service provider such as IBM Internet Connection Services, you can gain access to the Internet.
Simple installation and automatic network connection and registration make accessing the Internet easy for users with all
levels of experience. Easy-to-use graphical interfaces mask the traditional network complexities - allowing you to focus on the information and services that you want rather than spending time learning the nuances of networking.
Installing the Internet Connection for OS/2
Installing the Internet Connection for OS/2 is simple. Just insert the first Internet Connection for OS/2 diskette in your diskette drive, type A:INSTALL, specify the drive where you want to install the Internet Connection for OS/2, and select the Install push button. The installation program displays a progress indicator, which shows the percentage of completion for the installation.
Registering with a Service Provider
Registration and connection to the Internet is easy, too. The Internet Connection for OS/2 is pre-configured for registration
and connection to Internet Connection Services. If you want to use another service provider, the Internet Connection for OS/2 allows you to configure other connections. You will need to provide some additional configuration information such as the provider's phone number, a subnet mask, and default servers - all of which is supplied to you by your service provider.
Using the Internet Connection for OS/2
Once you have connected to a service provider, you can use the programs provided in the Internet Connection for OS/2 to:
Send electronic mail
Access online bulletin boards
Explore the Internet
Access information on other computers
Transfer files between computers
Create quick-access icons
Sending Electronic Mail
ULTIMAIL LITE provides an easy-to-use interface for creating, sending, and receiving electronic mail. UltiMail Lite supports the MIME protocol, which allows you to send multi-media mail such as video and audio clips.
Accessing Online Bulletin Boards
NEWSREADER allows you to share information with others using the various newsgroups on the Internet. A newsgroup is
basically an electronic conversation among people who share a common interest. You gain access to these newsgroups by
connecting to a USENET news server. On a USENET news server, you will find facts, opinions, and information on almost
any subject.
Exploring the Internet
GOPHER** provides a hierarchical, menu-driven interface to assist you in finding, displaying, and transferring information that is maintained on the Internet.
An abundance of information is available on the Internet - free software, the latest weather and news, directories of Internet
users, electronic books, forums, recipes, and more.
Accessing Information on Other Computers
TELNET and 3270 TELNET allow you to log in to other computers on the Internet. Once you are logged in, you can access
information and programs located on other computers.
Transferring Files Between Computers
FTP is an application that allows you to transfer data between your computer and other computers on the Internet.
Creating Quick-Access Icons
The Internet Connection for OS/2 also provides a set of templates. A template is an object that you can use as a model to
create additional objects. For example, if you use Telnet to frequently access three different computers, you may want to use
a template to create three instances of the Telnet icon, each with a different label and each connecting to a different computer

USENET is a large collection of computers that share data with each other. It is the people on these computers that make USENET worth the effort to read and maintain, and for USENET to function properly those people must be able to interact in productive ways. This document is intended as a guide to using the net in ways that will be pleasant and productive for everyone.
This document is not intended to teach you how to use USENET. Instead, it is a guide to using it politely, effectively and efficiently. Communication by computer is new to almost everybody, and there are certain aspects that can make it a frustrating experience until you get used to them. This document should help you avoid the worst traps.
The easiest way to learn how to use USENET is to watch how others use it. Start reading the news and try to figure out what people are doing and why. After a couple of weeks you will start understanding why certain things are done and what things shouldn't be done. There are documents available describing the technical details of how to use the software. These are different depending on which programs you use to access the news. You can get copies of these from your system administrator. If you do not know who that person is, they can be contacted on most systems by mailing to account "usenet".
The goal of this newsletter is to be informative and interesting. We hope we have achieved that goal. We welcome
comments and suggestions. Please send them to TCPIPNEWS@VNET.IBM.COM. Also, if you would like to be
notified via Email of new editions of the TCP/IP Connections newsletter, please send your name and Email address
