System Requirements

Open Transport/PPP is designed to work on Mac OS-compatible
computers with a Motorola 68030- or 68040-family
microprocessor, or a PowerPC 601, 603e, 604, or 604e

The recommended system software version for Open
Transport/PPP is 7.5.3 or later, updated with Open Transport
1.1.1. System software versions 7.1, 7.1.1, and 7.1.2
releases are also compatible with Open Transport/PPP updated
with Open Transport 1.1.1.

IMPORTANT: You must update your system with Open Transport
1.1.1 before installing Open Transport/PPP. See the
following section for information about updating to Open
Transport 1.1.1.

NOTE: Open Transport/PPP cannot be used with system software
versions 7.5, 7.5.1, or 7.5.2. Before installing Open
Transport/PPP on one of these systems, run the latest 7.5.3
(or later) system updater.

Open Transport/PPP 1.0 requires a mimimum of 500K of RAM
(for 68030- or 68040-based computers) or 600K of RAM (for
PowerPC-based computers). Open Transport/PPP memory
requirements are based on the size of total system memory,
including virtual memory, minus the size of any RAM disk or
disk cache you're using.

Open Transport Requirements

Version 1.1.1 of Open Transport is required for use with
Open Transport/PPP.

NOTE: The Open Transport 1.1.1 update, provided with the
Open Transport/PPP installer, requires that you already have
Open Transport 1.1. installed on your computer.

Here are the steps required to install Open Transport 1.1.1,
depending on the system software you have:

* System 7.1.x 1. Install Open Transport 1.1. (Can be

* System 7.5.3 if you have performed a custom installation
without installing Open Transport 1. Use the System 7.5.3 or
System 7.5.2, Update 2.0 installer to custom-install Open
Transport 1.1. 2. Install Open Transport 1.1.1 Update.
(Available free online, or can be purchased through February
1, 1997 for $13. Call 1-800-293-6617 and ask for offer

* System 7.5.5 if you have updated a system on which Open
Transport was not installed due to a custom installation. 1.
Reinstall system software using the system software disks
that came with your computer. 2. Based on the version of the
system software that came with your computer, use one of the
procedures above to install Open Transport 1.1.1.

Apple Software Update Sites

Information about updating Apple software is available
online on the World Wide Web and other online servers. On
the Web, go to either of the following sites:

Both of these sites provide links to the Apple Software
Updates page.

These sites also provide links to the Technical Info Library
(TIL). By searching for "find apple software updates" in the
TIL, you can find Apple Software Updates locations for
Internet, America Online, CompuServe and other online

Once you reach an Apple Software Updates site, use the
following path to locate the Open Transport software:

  Apple SW Updates
          Open Transport

Before You Install Open Transport/PPP 1.0

* Make backup copies of the software and documents on your
hard disk (especially your System Folder) before installing
this software.

* If you already use SLIP or PPP software to access the
Internet, make a note of the configuration information that
you entered into your previous SLIP or PPP control panels.
Configurations are not automatically converted from
third-party SLIP or PPP software.

Known Incompatibilities and Limitations

* Version 1.1.1 of Open Transport is required for use with
this release of Open Transport/PPP. You should not attempt
to use Open Transport/PPP with Open Transport 1.1.

* ARA 2.x modem CCL scripts can be used with Open
Transport/PPP. However, some ARA 2.x scripts do not support
modem-based error correction and data compression, so
performance may not be optimal. You should try to use one of
the modem scripts provided with Open Transport/PPP. If you
can't find one that matches your modem, you can modify an
existing script to suit your needs.

* If you are using both ARA 2.1 and Open Transport/PPP, be
sure to install Open Transport/PPP after ARA 2.1 to get the
correct set of modem scripts for both products.

* If you are running Open Transport/PPP on a desktop
Macintosh that has sleep capabilities, your Open
Transport/PPP connection will not be automatically
terminated when you select Sleep from the Special menu,
because sleeping desktop computers can continue network
activity (unlike PowerBook models). If you don't want to
remain connected to your PPP server when you put your
desktop system to sleep, disconnect manually using the PPP
control panel.

* If you have a copy of Open Transport/PPP older than
1.0f1c2 installed, you must discard your old Open
Transport/PPP preferences files. To do so, remove the Remote
Access folder from the active Preferences folder. Restart
your computer and then use the Modem and PPP control panels
to customize your configuration.

* Open Transport/PPP 1.0 has some incompatibilities with the
Apple Express Modem.  If the Internal Modem choice does not
appear in the Modem control panel Port pop-up menu, uncheck
the "Use internal modem instead of Modem/Printer port"
checkbox in the Express Modem control panel and restart.
Then open the Modem control panel again.

* You may experience some difficulty with older programs
that do not use Open Transport and try to use the serial
port while PPP is active. The workaround is to disconnect
PPP using the PPP control panel before starting up the
serial application.

* Claris Emailer version 1.1v3 or later is compatible with
Open Transport 1.1.1. A problem in the Quit command of
earlier versions of Claris Emailer sometimes causes a crash
with Open Transport 1.1.1 (with or without Open
Transport/PPP). For your convenience, the Claris Emailer
version 1.1v3 patcher and Claris Emailer Lite version 1.1v3
patcher have been provided in the Open Transport Extras

* You may experience CD and TV sound problems when you are
dialing your Internet service provider from a Performa
6300CD computer. The workaround is to launch Megaphone
before trying to connect.

* When entering phone numbers for the Motorola BitSURFR Pro
56K and 64K ISDN terminal adapters, do not use dashes or
spaces between the numbers. For example, "555-9999" should
be entered as "5559999". Entering spaces or dashes may
prevent successful connections with the BitSURFR Pro,
particularly when two ISDN channels are used.

* If you use PortShare Pro from Stalker GmbH to set up a
virtual modem or virtual printer port, the ports appear as
Modem or Printer, respectively, in the Modem control panel.
They do not appear as Virtual Modem or Virtual Printer.
PortShare Pro replaces the serial drivers for the on-board
modem/printer ports with its own, so selecting Modem or
Printer causes Open Transport/PPP (and any other native Open
Transport serial application) to use the replacement

* Open Transport/PPP will report the single channel speed of
56Kbps or 64Kbps. The 112Kbps or 128Kbps speeds are used but
not displayed when using a second ISDN channel with
multilink PPP. Use the terminal adapter to find out the
speed of the second channel.

Compatibility with the Apple Internet Connection Kit

You can install both Open Transport/PPP and the Apple
Internet Connection Kit (AICK) on your computer at the same
time. Both products enable you to dial with your modem and
connect to the Internet.

At the time of this release, AICK does not use the Open
Transport/PPP software to dial and connect to the Internet.
AICK has its own Dialer, which uses MacPPP software to
establish the remote connection. MacPPP is a third-party
implementation of the Point-to-Point Protocol.

All of the AICK applications, however, are compatible with
Open Transport/PPP 1.0. To use Open Transport/PPP with AICK
applications, you must configure Open Transport/PPP as
described in the Open Transport/PPP User's Manual and in the
"Connecting to the Internet" topic area of Macintosh Guide.

The currently active PPP software is selected using the
"Connect via" pop-up menu in the TCP/IP control panel.
MacPPP is listed as MacPPP. OT/PPP is listed as PPP. MacPPP
is controlled by using the ConfigPPP control panel, the
Apple Internet Dialer application, or the Apple Internet
Status application. Open Transport/PPP is controlled by
using the Modem and PPP control panels, which do not modify
or change MacPPP configuration information.

If you use both PPP software packages (one at a time), note
that launching either the Apple Internet Dialer or Apple
Internet Status will make MacPPP active. Furthermore, you
will need to switch TCP/IP configurations each time you
switch from one PPP software package to the other.
(Information about changing TCP/IP configurations appears in
the Network topic area of Macintosh Guide.)

Interactions with Third-Party Software

Netscape 2.x will not work reliably with versions of the Mac
OS before System 7.5.3 or versions of Open Transport
software before 1.1. If you would like to use Netscape 2.0.1
or later, you should make sure that System 7.5.3 or later
and Open Transport version 1.1.1 or later are also used.
Failure to follow this recommendation may result in system

Apple now installs all modem scripts in the Modem Scripts
folder (in the Extensions folder) instead of directly in the
Extensions folder. Future Apple products will handle modem
scripts the same way. Open Transport/PPP does not recognize
modem scripts stored outside the Modem Scripts folder.

Auto-routing of modem scripts has been disabled by the
installer. Once Open Transport/PPP is installed, a modem
script will not be routed to the Extensions folder if it is
dragged into an active System folder.

The Easy Install mode of the installer copies all of the
Open Transport/PPP modem scripts to your disk. You can
choose Custom Install to limit the installation to only the
scripts you choose.

NOTE: You can delete any unneeded scripts from the Modem
Scripts folder, which is located inside the Extensions
Folder. To recognize scripts, look for files labeled as
"Modem Link Tool Personal document."

Additional (Unsupported) Modem Scripts

User-contributed scripts are available online. New modems
are regularly introduced and Apple is willing to help
publish scripts donated by users to aid in making Apple
Remote Access and Open Transport/PPP work easily with as
many modems as possible.

IMPORTANT: User-contributed scripts are not tested or
supported by Apple Computer, Inc., so you should contact the
script's author rather than Apple if you run into difficulty
using a script downloaded from the unsupported folder.
User-contributed modem scripts are provided on an as-is
basis as a convenience to Apple customers. They are not
warranted to be complete or free from errors, although Apple
may choose to review and fully test some user-contributed
scripts and include them in future versions of Apple
software. If you want to provide Apple with feedback about
particular user-contributed scripts, send electronic mail to
the following address:

To find these scripts, go to any Apple Software Updates
location and use the following path:

  Apple SW Updates

If you you want to contribute a modem script, please use the
following procedure:

1.  Download the sample Read Me file from the
User-contributed scripts folder. The file is named
CCL_README_TEMPLATE. 2.  Customize the sample Read Me as
appropriate for the script you want to submit. 3.  Send
electronic mail to  and enclose the script in
bin/hex format.

Scripts will only be posted if they are accompanied by a
Read Me explaining the script's purpose and how to contact
the author.

(See "Apple Software Updates Sites" near the beginning of
this Read Me for information on how to find Apple Software
Updates locations.)

Modem Cable Requirements

Most modems require a cable that supports the data terminal
ready (DTR) signal. In addition, certain modems require a
cable that supports CTS/RTS hardware flow control. To
support DTR, the cable must connect pin 20 on the DB-25
connector to pin 1 on the Mini DIN-8. To support CTS/RTS,
the cable must connect pin 5 on the DB-25 connector to pin 2
on the Mini DIN-8 and pin 4 on the DB-25 connector to pin 1
on the Mini DIN-8. Contact your modem vendor or
Apple-authorized dealer to obtain the necessary cable.

Open Transport/PPP and Apple Remote Access Compatibility

Open Transport/PPP and ARA versions 1.0, 2.0, 2.0.1, and 2.1
are fully compatible and can be used on the same system.
Only one can be used at a time.

Versions of ARA before 2.1 install modem scripts directly in
the Extensions folder. To make sure that these scripts
appear as choices in the Modem control panel, move them to
the Modem Scripts folder in the Extensions folder.

ARA 2.1 installs its scripts in the Modem Scripts folder
with Extensions. If you are using ARA 2.1, you must install
Open Transport/PPP after ARA 2.1 to get a set of scripts in
the Modem Scripts folder that works optimally with both
products. The Open Transport/PPP scripts support certain
modem-based features, such as error correction and data
compression, that improve PPP performance. The ARA 2.X
scripts may not support these features.

Also, some scripts included with ARA 2.1 are no longer
installed with Open Transport/PPP. These scripts are left on
your disk by the Open Transport/PPP installer. They may be
usable with Open Transport/PPP, but have not been tested for
compatibility by Apple.

Registered User or Guest?

If your PPP server does not require a user name and
password, or if the server requires only that you enter a
name and password in a terminal window, you can select the
Guest mode button in the PPP control panel. This will hide
the Name and Password fields and will cause the Connect
button to be enabled as soon as you enter a phone number.

If your server requires a PPP user name and password instead
of, or in addition to, a terminal server login, you must use
the Registered User mode of the PPP control panel. In this
mode, you must enter something in the Name and Number fields
to enable the Connect button. If you leave the Password
field blank, and "Save password" is not checked, you will be
prompted to confirm that you want to connect without a

Connect Scripts

The following varStrings have been added to the CCL
scripting language for the user name and password:

Name:          ^11 or ^U
Password:     ^12 or ^P
When the connect script is executed, these varStrings are
substituted by the strings stored in the Name and Password
fields of the PPP control panel.

When you record a connect script, and you have entered your
name and password in the PPP control panel, the connect
script that's recorded by the terminal window will replace
those strings by the appropriate varStrings.

The ^U and ^P varStrings are provided as mnemonics for the
user name and password, but they cannot be used as
parameters of some CCL commands like IFSTR. With those
commands, use the ^11 and ^12 varStrings instead.

Connection CCL scripts that use the password varString (^12)
in WRITE commands do not log the password in clear text. The
password is logged as bullets. This is true whether the user
records the script or types it in.

More detailed information about the syntax of the CCL
language used for both modem scripts and connect scripts is
in the ARA Modem Scripting Guide.PDF file in the OT/PPP
Extras folder. This file is in Adobe Acrobat format.

Manual Dialing

Procedures for stablishing an Open Transport/PPP connection
with manual dialing vary according to the type of modem you
are using. To ensure that you can make a connection while
using manual dialing, you may need to experiment with
pressing the Connect button slightly before or after you
hear the remote modem answer the phone.

Using an Express Modem or GeoPort Telecom Adapter

If you are using Express Modem software with either an
Express Modem or a GeoPort Telecom Adapter, you must turn on
32-bit addressing in the Memory control panel. Using 24-bit
addressing may result in incorrect behavior.

Using Global Village PC Card Products

The Global Village software included with your modem adds an
entry to the "Connect via" pop-up menu of the Modem control
panel called "PowerPort PC Card". Under some circumstances,
an entry for the actual slot your PC Card is plugged into
will show up as well ("Upper-slot", "Lower-slot"). These
slot-specific items should not be used and the "PowerPort PC
Card" item should be used instead or the port will be
erroneously reported as busy.

Using an ISDN Terminal Adapter

Both Open Transport/PPP and ARA 2.1 support serial
connection speeds of 115,200 and 230,400 bps. By doing so,
Apple enables Macintosh users to make ARA and PPP
connections over ISDN lines at 64 kbps or even 112 kbps if
the ISDN terminal adapters at both ends support channel
bonding and proper modem scripts are used.

NOTE: The "Connected at" line of the PPP control panel
status box may not accurately reflect the connection speed
of ISDN connections. A slower speed may be indicated because
ISDN terminal adapter hardware does not report the
establishment of second channel connections to the CCL
script engine. This will usually happen if you use the
Multilink PPP (MLPPP) version of an ISDN script.

Connection speeds of 115,200 and 230,400 bps are not
supported by the serial ports on most older Macintosh
computers. Here is a partial list of Machintosh models that
do have fast serial port support:

* Macintosh Centris 660av, Macintosh Quadra 660av and
Macintosh Quadra 840av models
* Macintosh Performa 6100CD series
* Power Macintosh 6100, 7100, 7200, 7500, 7600, 8100, 8500,
and 9500 models
* Workgroup Server 6150, 7250, 8150, 8550, and 9150 models

To set the built-in serial ports at 115,200 or 230,400 bps,
a new serial driver called SerialDMA must be installed to
replace the standard Macintosh serial device driver.
SerialDMA is provided by Apple, and the current version is
2.0.2. It is highly recommended that the file Serial
(Built-in) be installed in the Extensions folder as well on
Macintosh models with PCI slots to support these high speeds
(38,400 bps and above). System 7.5.3 or later includes the
latest version of SerialDMA and the file Serial (Built-in).

NOTE: In general, ISDN terminal adapters have more
configuration options than conventional modems. At this time
it is not possible for Apple to support all combinations of
these options for all the ISDN terminal adapters that are
supported. We have attempted to write scripts that work with
the most common ISDN configurations. You may have to get a
revised script from your Internet service provider or
network administrator if your server uses different options.
You can also modify a script yourself using the Modem Script
Generator or by editing the script text directly.

How to Turn Off or Remove Open Transport/PPP

To disable and remove Open Transport/PPP software by using
the Custom Remove option in the Installer, follow these

1. Open the Installer application included with Open
