OS/2 Warp 4.0 Dial-up Configuration Instructions

House Keeping

If you the subscriber are new to the OS/2 Warp4 TCP/IP and Remote Access Client environment, the installation of these options provides for client services to an Internet service provider.

The install process includes client applications (WebExplorer, Ultimedia Mail, NewsReader, and utilities such as Telnet, FTP, Gopher, etc. Each client program will work with either provider based on the selection of the dialer selection indicated by a radio button (IBM Internet or Alternate - i.e. Xmission).

IBM has included dialer functions pointing to their network (Advantis) as well as to other Internet providers. This readme will focus on the latter and assumes you have already installed the TCP/IP services and Remote Access Client with the Warp4 install process. Connectivity to Xmission will be via ppp/pap (Password Authentication Protocol).

Getting Started

Before beginning with the TCP/IP functions, please locate the set TZ=EST5EDT and set hostname statements in your config.sys and change it to set TZ=MST7MDT and the set hostname to set hostname=_your_userid_

Save the file and re-boot your system.

Using Password Authentication Protocol with PPP

1. Configure an Internet connection using Dial Other Internet Providers (DOIP) using a stand alone machine. Using the dialer is a very simple way to use PAP (Password Authentication Protocol) as by design, it is the default of the program.

2. Set up the dialer.

Double click the Programs Icon. Double click the Internet (modem) Icon. Double click the Dial Other Internet Providers Icon. Click on the Add Entry button.

Initialization String 1:	(default or your informed selection)
Initialization String 2:	(default or your informed selection)

3. Now close the Add Entries folder, choosing the save option.

4. Click on the Dial button.

If you get an Unsupported protocol (80fd) message, it can be ignored.

5. Assuming you now have a connection, try using some client applications; Ultimedia Mail, NewsReader, Webexplorer, etc.

Each client application has help functions for additional information. If a window opens indicating you are not connected to the Internet, be sure to select the Alternate radio button before making your connect selection.

Ultimedia Mail may prompt you to verify information. Once the program is running, you can set your time zone, signature, and reply to information via the Mail Cabinet | Cabinet | Settings book. If you have any trouble with the log_on window, see the help information below and pointer to an IBM help for Ultimedia at their WEB site, below. Also if you experience a problem where Ultimedia Mail can not be started multiple times between boots, try dragging a copy on Internet (Modem) to the WarpCenter.

The NewsReader when first started will prompt you to load a list of news groups in order for you to make a selection(s) of the groups of interest. Double clicking a group will cause it to be selected. Also view the different parts of Options and Configure to make choices that meet your needs.

WebExplorer is pretty easy to use. If your wish to get rid of the announcement and shutdown query you can add a -q to the parameters line in the program properties. The number of threads can also be changed from the default of 4 to a maximum of 8; again on the parameter line add -t n where n is a number from 2 to eight (e.g. explore.exe -q -t 8).

Other considerations


The IBM dialer does not have re-dial capability needed when the modem responds with a busy signal or ring-no-answer, etc., in this case the user must manually initiate a re-dial. There is; however, a script, 'pppdial.cmd' available which can be used to resolve this problem. As of today, this script is shareware (free); you may get information about it via your WebExplorer at:


A copy of ppdial29.zip is also included in this library.

Because the script's install process is designed to sense information about your current setup, it is recommended you do this after you have gone through your dialer set-up. After installing the script, change the Login Sequence field on Login info page from NONE to

pppdial.cmd x:\mptn\bin\your_file_name

Below is an example of what my pppdial response file (\mptn\bin\rspfile.pap) consists of in conjunction with a pap connection.

<span class="button">PPPDIAL_USE_DIALER</span>
<span class="button">PPPDIAL_INIT1</span> AT&F1
<span class="button">PPPDIAL_INIT2</span> ATS7=30S11=55

Note that I chose to use the fields in the dialer with the exception of the modem settings because I thought it was cleaner. These commands are for my USR Courier; if you are using something else, be sure to check with your manufacturers manual.


This neat little utility (nistime.zip in this library) will allow you to keep your PC's clock in sync with xmission and the rest of the world. Be sure to put a set SET TZ=MST7MDT statement in your config.sys. I have used this program with both Warp3 and Warp4 without incident. I use the following in execution.

      nistime.exe -m2 -s1


There are many WWW sites available that can provide help and information regarding the use of OS/2 Warp and the Internet, but each of us have our own preferences, so I'll leave discovery of this subject open, except for the following. With over 20 months of Internet use with Warp3 and Warp4 I've only found four really useful sites other than the Usenet comp.os.os2.* groups. They are (I may have not pointed to a home URL) :

Netscape for OS/2 Warp

With the recent agreement between IBM and Netscape, an OS/2 version of the Netscape WEB browser has been made available. If you care to try this as an alternative (or in addition) to WebExplorer have a look at


or use the get NetScape Icon in your folder, where you can download a copy and other options, free.

Notes Mail

With the acquisition of Lotus by IBM, Notes Mail is now available for use with Warp4. Since Xmission uses a POP mail server and if you have an interest in this product in place of Ultimedia Mail, use your WEB browser to checkout




If you decide to try Notes Mail, you install it from the CD that came with Warp4. The WEB sites provide additional information over and above that on the CD.
