Instant communication

You can use electronic mail (e-mail) to communicate with people around
the world instantly. Millions of people worldwide are using e-mail for
everyday communications because it's less expensive than a phone call or
fax and faster than a postal carrier.

To reduce costs even more, you can process mail offline and avoid paying
for network access.

New worlds and old

Internet resources are linked together through the World-Wide Web (WWW).
With WebExplorer Mosaic, included in IBM Internet Connection for
Windows, you get a powerful yet easy-to-use interface for exploring the
WWW.  WebExplorer Mosaic lets you explore the Internet by clicking on
highlighted text or graphics to go from one page to the next.

On each page, you'll see information presented as text, pictures and
photographs, sound, or even video clips. By moving around the Internet
with WebExplorer Mosaic, you get the opportunity to visit new worlds and
old - science, entertainment, or art. And everyday business can be
extraordinary.  Paths through the Internet IBM Internet Connection for
Windows includes the Windows Internet Gopher. Through menus and other
linking options, Gopher makes accessing Internet resources as easy
as borrowing books from the local library. Add bookmarks so you can find
information quickly the next time.

No matter where Gopher servers are located, you can display and transfer
the information right to your personal computer - usually within a
matter of seconds.  You can get free software, electronic books,
recipes, and up-to-the-minute news and weather reports - anytime,
anywhere.

Internet newsgroups

NewsReader lets you share information with others across the Internet
through newsgroups. By joining newsgroups, or discussion groups, you get
the opportunity to communicate with others on well-known topics or
obscure subjects.  Internet newsgroups discuss any number of topics -
like art, sports, politics, computers, and hobbies - and include facts,
opinions, and information you can't imagine.  The IBM Internet
Connection for Windows NewsReader provides a graphical user interface to
help you manage information, and organize and subscribe to newsgroups.
Copy and print interesting articles when you want to.

No more books

Don't worry about documentation. IBM Internet Connection for Windows
gives you more than 100 pages of online help right at your fingertips.
With this kind of help, finding answers is just a click away.

IBM Internet Connection for Windows - Helping You Voice Your Opinions

Recently, IBM teamed up with Kinko's, the nation's largest retail chain
of document and reproduction centers, to allow people without Internet
access to participate in an electronic forum entitled "People and Their
Governments in the Information Age".  This open on-line town meeting
took place May 1-14 and was designed to solicit feed-back from the
public on topics such as the changing role of local, state, and
federal governments.  IBM aided in making this first of its kind
meeting become a reality by providing the IBM Internet Connection for
Windows and access to the IBM Global Network to the participating
Kinko's locations.

Focus on the Customer.... A Continuing Theme

One of the activities our TCP/IP for MVS team is engaged in for '95 is a
Post GA customer call campaign to talk with our customers who have
installed TCP/IP V3R1 for MVS.  Currently, we have talked with 30
customers.  11 of them are new TCP/IP users.  The remainder are
customers who have migrated from TCP/IP 2.2.1.  IBM participants
in the post GA customer calls come from three groups:  Human Factors,
Information Design and Development, Product Design, Development, and
Marketing, which includes a range of expertise from performance, build,
and test, to service and support.

The main purpose of the calls is to make sure that things are going
smoothly with V3R1.  If there are any concerns that our customers
have, we try to address those concerns during the call.  If that is not
possible, we follow up and get back to them as soon as possible.
The customers we've talked with have had many positive experiences
to share.

  Previous and new customers alike are very happy with the
    documentation.  They're glad to see error messages identified and
    numbered.

  Customers who upgraded from V2.2.1 said the migration went smoothly
    and was straightforward.  They appreciated the migration and planning
    manual.

  Customers new to TCP/IP for MVS were impressed with the ease of
    installation.

  Having the config files in one place was a welcome improvement to the
    configuration process.

  Another improvement that customers noted was the enhancement to
    Netstat.  They like the fact that there"s now more information
    available.

  Other features mentioned often were the VTAM MSG 10 and USSTAB, time
    stamping of WTO messages, IP to LU mapping, and packet tracing.

If you have installed V3R1 and would like to be on our list of post GA
customers, please send your name and phone number to Brenda Rubens
([e-mail]).
Although we cannot guarantee that we will call you during our Post GA
call campaign, we would appreciate hearing from you.

What's New with the X Window System Server?

We're happy to report that significant text performance improvement is
available for our X Window System Server (PMX) V2.0 customers.  The
latest CSD for PMX is UN68122. You can access this CSD via anonymous
ftp from software.watson.ibm.com and many other locations that mirror
it.  The CSD contains new PMX font technology, as well as other fixes
to PMX.  Consult the readme.1ST and readme.pmx files for details.
(PMX CSD UN68122 should not be used before applying CSD UN64092 to the
TCP/IP OS/2 Base Kit.)

Introduction to PMX fonts

Readers of this newsletter have asked for information on PMX font
administration.  The following information is an overview of
PMX fonts.  To get a complete understanding of fonts in X servers,
official documentation on the X Windows system should be
consulted.  (Reference the Bibliography section for specifics.)
X Fonts are distributed as files.  The file name extension indicates the
format of the font.

*.bdf   "Bitmap Distribution Format"

This is a font source. It is in ASCII format, and can be read by people.
To use this font with PMX, it must be compiled into a binary format.

*.pcf   Portable Compiled Format

This is a binary format, new to X11R5.  These fonts can be transferred
across machines and used without recompiling, even if the machine
architectures differ.

*.xfn   PMX specific format X Font

PMX provides utility programs to create this font format.

*.snf   Server Natural Format

This is an obsolete binary format.  It was used prior to X11R5.  PMX
does not support this obsolete font format locally.  PMX can use this
font format only via a font server.

*.spd   Speedo format
This is a binary format, new to X11R5.  These fonts are outline fonts,
similar to Adobe fonts (as opposed to bitmap fonts).


Fonts are typically stored in file system directories.  As an
alternative, fonts can be stored on font servers (X11R5 and later)
and accessed via the TCP/IP network.  PMX is capable of accessing fonts
stored on font servers.

The fonts an X server can access are controlled via the font path
parameter.  The font path is an ordered list of font directories
and/or font servers to access to satisfy X client font requests.  For
PMX, the font path can be specified on the OS/2 command
line (-fp ) or can be set in the PMX configuration notebook pages.
Each font directory on the font path must have a database of PMX fonts.
The database must be named fonts.dir.  The fonts.dir is a flat ASCII
file, which is created by the mkfontdr.exe tool (mkfontdir on AIX/UNIX).
Fonts.dir is a table with file name and XLFD (X Logical Font
Descriptor) name columns.  An XLFD name is a string containing no
more than 14 fields that describe the font.  The XLFD name is used by
X clients and X servers to specify fonts.

How to add fonts to PMX

1.    Choose a directory to hold the new fonts.
2.    If necessary, compile the fonts into the proper format.
   A)    *.bdf fonts    bdftopcf.exe creates .pcf font binary.
                        bdftopm.exe creates .xfn font binary.
   B)    *.pcf fonts    pcftopm.exe creates .xfn font binary.
3.    Run mkfontdr.exe to update (or create) the fonts.dir file.
4.    Add the directory to the PMX font path, if missing.
5.    Force PMX to reaccess the font path
A.    Run xset fp rehash
B.    Select Reset Server from PMX Server Window Menu.
C.    Stop and restart PMX.

How to access fonts via a font server

Add a font server name to the PMX font path.  Names are specified as
transport/hostname:port The transport is tcp.  The default port for
X11R5 font servers is 7000.  For AIX, the default port is 7500. The
default for X11R6 font servers may differ.  Consult the PMX on-line
publications for further information.

Useful font server client programs:

  fsinfo.exe - A client that connects to a font server and displays
information.  Useful to determine if a font server process
is running on the remote host.

  fslsfnts.exe - A client that connects to a font server and lists
available fonts.

  fstobdf.exe - A client that connects to a font server and creates a
.bdf font source file on the OS/2 file system.  To use
the font locally, follow the steps in How to Add Fonts to PMX.

What's in a name

As mentioned above, fonts in the X Windows System are specified with a
XLFD name.  The real XLFD name for the font is
listed in the fonts.dir file.  At times it is convenient, even
necessary, to access the same font by a different XLFD name.  This
is accomplished by alias names.  Alias names are created in the
fonts.ali file (fonts.alias on AIX/Unix).  There can be more
than one fonts.ali file, but each fonts.ali file must be located in a
directory listed in the font path statement.  PMX merges each
fonts.ali file found in the font path into a single memory-resident
table.

Using OS/2 PM Public fonts with PMX

OS/2 PM comes with a variety of bitmap and scaleable fonts.  Installing
word processor or graphics editing packages on OS/2
usually adds more PM Public fonts that can be used by any PM application
on your OS/2 system.  After CSD UN68122 is applied, PMX allows
X applications to use of all these PM Public fonts (when pmpublic\
is added to the PMX font path).  Because the contents of the PM Public
font list is subject to change, PMX creates a fresh list of public
fonts each time pmpublic\ is activated.  It does this by running
mkfontdr -pmpublic as a child process. mkfontdr -pmpublic creates a
fonts.dir file in the subdirectory pointed to by the ETC environment
variable. (pmpublic\ is not automatically added to your PMX font path).

PMX will also use a fonts.ali file if it is found in the same ETC
subdirectory with the fonts.dir file for the PM Public fonts.  PMX
does not ship a fonts.ali file for PM Public fonts.

Limitations of the *.xfn font format

X Servers, including PMX, are capable of scaling bitmap fonts (*.pcf),
but OS/2 PM does not scale bitmap fonts.  With the present
implementation, a font request for a bitmap font in .pcf format
at an arbitrary size will usually succeed (although the
resulting font may have a jagged appearance).  However, a font request
for a bitmap font in .xfn format will only succeed for the size at
which the font was encoded.  (PMX does not scale .xfn fonts.)
To resolve this situation, the .pcf font format can replace the .xfn
font format (run mkfontdr.exe after replacing the font).
Drawing text with .pcf fonts will be slower than the .xfn format, but
the request should succeed.

If the font is available on a font server, the fstobdf.exe utility could
be used to extract a local copy of the bitmap font, at the
size specified in the XLFD name.  The resulting .bdf font would be
converted to .xfn following the steps outlined above.

Correcting font failures

When font requests cannot be satisfied by an X server, error messages
are usually issued.  A common message is ...unable to convert
FontStruct...".  To get more information on failures, PMX supports
a command line "-logfonts" parameter.  Logfonts can also be specified
in the configuration notebook pages.  The logfonts parameter causes
PMX to record all font requests, including the XLFD name, and
responses. The information is written to the PMX.LOG file.
The typical reason for failure is no match was found on the requested
XLFD name.  Please refer to the Limitations of the *.xfn Font
Format" section.  Quite often the only solution is to supply the
missing font to PMX.  This can be done by accessing a font server,
or by supplying a local copy.

A possible short-term solution is to use the fonts.ali (name alias) to
map the XLFD name that fails to an available font XLFD name with
similar properties.  Another possible approach is to customize the
X client, specifying alternate fonts or font sizes.  The technique
may differ for each client, but it typically involves changing the
X resource settings for the X client program.

PC Magazine Review of Web Explorer

The following is a review of the OS/2 Web Explorer from the February
7th, 1995, issue of PC Magazine.

Web Explorer
  By:  Amarendra Singh

A few of the packages in this roundup require you to change your TCP/IP
stack,  but IBMs Web Explorer is the only one that asks you to change
your operating system.  Web Explorer is part of a package of Internet
tools and services called IBM Internet Connection for OS/2 that IBM is
essentially giving away with the new OS/2 Warp, Version 3.

As of November, this product was freely available only as a prerelease
version; upon completion it will be freely available to all
OS/2 Warp users.  To get Web Explorer (now or when its finalized), just
click the Update Software icon in the Internet Access group
of OS/2 Warp's interface and the program will be downloaded from
the Internet.  Those with earlier versions of OS/2 can download
the browser at ftpq1.ny.us.ibm.net.

As of this review - and as far as we or IBM knows - Web Explorer is the
only native OS/2 Web browser on the market.  Built from the ground up
by the folks at Big Blue, it's neither a rehash of an existing
Windows-based product nor a minimalist make-do.  WebExplorer is a
a complete, full-featured browser designed to take specific advantage
of the operating system.

IBM has done an excellent job of making connections to its Internet
access service (the IBM Global Network, also called
Advantis) transparent to users.  Setup is no more complicated than
filling in a couple of details about your system and location.
Once it has the necessary info, the system dials out and  registers you
automatically.

You can, of course, use Web Explorer with other access providers, but
you're on your own if problems crop up.  Web Explorer's extensive
on-line help doesn't deal with non-IBM connections.  (Although IBM
has clearly designed the product  with modem-based connections in
mind, Web Explorer can also be used with a direct LAN-based
TCP/IP connection.)

POINT YOUR COMPASS

OS/2 Warp's browser is easy to navigate:  Buttons and pull-down menus
guide you effortlessly through the Web and its services.  When
navigating between several loaded documents, you can move backward
and forward with the click of a button.  Like most of the products
we tested, Web Explorer lets you store your favorite home pages in
an easily accessible hotlist.  Web Explorer (like Frontier Technologies'
WinTapestry) goes beyond standard capabilities to let you access
multiple Web pages simultaneously, but OS/2 Warp's multitasking
capabilities make the process smoother than with other products.
You can even run multiple sessions of Web Explorer simultaneously.

CONFIG CINCH

The Web Explorer is also easy to configure.  A pull-down menu lets you
customize everything from font sizes and colors to the use of your own
applets for file viewing.  In addition to Web Explorer, IBM's Internet
Connection for OS/2 provides a complete set of native OS/2 tools for
accessing Internet services.  The list of applications includes
e-mail, FTP, a news reader, and telnet.  Despite the fact that it is
quite literally in a category by itself, WebExplorer is clearly going
to be a major contender in the Web browser arena.  It may be the only
OS/2 game in town, but it's definitely one you'd want to play in.
We strongly recommend that all OS/2 users check it out.  Of course,
you can't run it under Windows.  But if IBM smiles and says
That's the point, you can hardly blame them.

At Your Service

This portion of our newsletter contains some frequently asked questions
and their answers.  If you have questions that you would like to see
answered in this newsletter, please send them to [e-mail].


o Does TCP/IP 2.0 work on WARP?

We are testing this, and we haven"t found any problems.  This is a
supported combination, meaning that we will fix any problems that do
arise.

o Does the IBM Internet Connection kit work with OS/2 2.1?

No.  The IBM Internet Connection kit can only be installed on OS/2 Warp.

o I have OS/2 2.1 and TCP/IP 2.0.  Can I run WebExplorer and Gopher?

Yes.  You must have CSD UN64092 installed.  WebExplorer can be
downloaded from the Internet, via anonymous FTP to ftp01.ny.us.ibm.net,
where it is in the subdirectory /pub/WebExporer.  Gopher can be
downloaded from the Internet, via anonymous FTP to
software.watson.ibm.com, where it is in the subdirectory /pub/os2/ews.

o I have OS/2 Warp.  Can I use the IBM Internet Connection kit for
   TCP/IP LAN access?

No, the IBM Internet Connection kit only supports dial access.  You
must install TCP/IP 2.0 for LAN based TCP/IP access.  A follow-on
to OS/2 Warp is in the works that will include full LAN enablement.
(There will be an upgrade charge.)

o The icons of the IBM Internet Connection kit are configured to use
    a dial connection.  How do I use these applications on the LAN?

Create program objects for WebExplorer (explore.exe) and Gopher
(gopher.exe) in your TCP/IP folder.

o The UltiMedia Mail Lite package included with the IBM Internet
    Connection kit is configured to be used with an Internet mail
    box.  How do I use it on the LAN?

For LAN based mail, use the LaMail package that ships with TCP/IP 2.0.

o Can I install both TCP/IP 2.0 (for LAN access) and the IBM
    Internet Connection kit?

Yes.  This combination is not tested or supported, but it does work.
You must install TCP/IP 2.0 first.  Then, install CSD UN64092.  And
finally, install the IBM Internet Connection (in the same directory
where TCP/IP 2.0 is installed).

The following questions arise when a user tries to use Internet
and LAN TCP/IP access simultaneously.  These problems do not occur
unless you try to access TCP/IP hosts on a LAN at the same time that
you have an active dial connection to the Internet.

o I want to access TCP/IP hosts on the LAN and via a dial connection
    to the Internet simultaneously.  When I dial the Internet, I can
    no longer get to the LAN TCP/IP hosts.  The error message is
    "host unknown.  What do I do about this?

While you are connected to the Internet, TCP/IP name resolution
queries a host name server on the Internet to look up host
addresses.  The Internet name server will not know the names of
your local hosts.  You can use the TCP/IP Configuration Notebook
to create a hosts file (page 3 of the services section) for hosts on
your LAN.  Or you can access hosts on your LAN by IP address instead
of by name.

o I have a default route to a router on my LAN.  When I dial the
    Internet, the LAN default route is inactivated, and I can no
    longer access TCP/IP hosts through my LAN router until I hang up.
    What do I do about this?

While you are connected to the Internet, your default route is to
the Internet.  You can create host, network, or subnet routes for
TCP/IP hosts that you access through your LAN router, so that these
hosts remain accessible while you are connected to the Internet.
You use the routing page of the TCP/IP Configuration Notebook.

Are You Behind the Times?

Have you ever encountered a problem in a product, spent hours trying to
determine the origin of the problem, only to discover that a fix for
the problem was made available months ago?  Well, to help you avoid this
situation,  we are including a list of the latest CSDs for TCP/IP.
This way you can ensure that you always have the latest.

An Easier Way to Obtain Fixes

Did you know that you can obtain Corrective Service Diskettes (CSDs)
electronically?  If you have access to the Internet, you can
FTP as Anonymous to SOFTWARE.WATSON.IBM.COM.

  Fixes for TCP/IP for OS/2 are located in pub\tcpip\os2.
  Fixes for TCP/IP for DOS are located in pub\tcpip\dos.

You can also obtain CSDs via modem connection from the NCSBBS bulletin
board at [phone].  Set your modem settings to: none,8,1.
