- Summary:
- Introduced in the fall of 1990, the TelePort broke Macintosh
- convention by being the first peripheral other than a keyboard or
- pointing device to take advantage of the Apple Desktop Bus. Almost
- a year later, here's a look at this still-innovative modem.
-
-
- Hardware & Software Requirements:
- The TelePort modem works fine on any Mac with ADB, in other words,
- the Macintosh SE and up. Compatible with System 6 and 7.
-
-
- Price and Availability:
- The TelePort is widely available from dealers and mail order
- firms, and MacConnection sells it for $139. The TelePort/Fax is
- slightly more at $185. (Note that we quote the MacConnection price
- in recognition of its industry-leading efforts to use
- ecologically-conscious packaging and its overall excellent
- service.)

- TelePort Capabilities
- ---------------------
- The coolest Macintosh telecommunications gadget is the TelePort
- modem from Global Village Communications. Global Village has
- created a small, unobtrusive modem that doesn't need a power cord
- and won't even take up one of your serial ports. It's a 2400 bps
- modem, complete with MNP capabilities through level 5 for error
- correction and data compression. There's even a 9600 bps fax
- version that lets you send faxes right from your computer (fax
- receiving has not been implemented in the current crop of
- TelePorts).
-
- An Apple Desktop Bus (ADB) device, the TelePort plugs into the
- computer the same way your keyboard, mouse, or trackball does, at
- least on the Macintosh SE or later. Either the spare ADB port on
- the back of your computer or the one on the side of your keyboard
- will work fine. For computers with only one ADB port, like the
- Macintosh Classic, LC, or IIsi, the TelePort comes with an ADB
- "Y-splitter" that lets you connect two devices to one port.
-
- Not only does the TelePort communicate with the computer through
- the rarely-used ADB channel, it also takes its electrical power
- from the ADB. While the ADB normally provides power and
- communications only to the keyboard and mouse, Apple originally
- intended it to support other devices from third-party developers.
- Other than keyboards and mice or mouse-replacements, the TelePort
- is the first. The TelePort should work just fine with any other
- ADB devices that come to market, though the ADB could be overtaxed
- by too many devices talking at once. At worst, this would slow
- down communications a bit.
-
- Because the TelePort is a Communications Toolbox (CTB) compatible
- peripheral, any communications software that knows how to work
- with the CTB can simply access the TelePort directly.
- Unfortunately, most older communications software was designed to
- work only with the modem port or printer port, and lacks a setting
- to talk through the ADB port. CTB-savvy software includes
- VersaTerm, MacTerminal, PacerTerm, uAccess, QuickMail 2.5, and a
- couple of shareware offerings, and a CTB-aware update for
- Microphone II is in the works. Global Village solved this problem
- for older software by writing special driver software in the form
- of a system extension that can be set to fool the Mac into
- watching for software that tries to access either the printer or
- modem port, and rerouting the communications to the TelePort. The
- user can decide which of the two serial ports will be "shadowed"
- by the TelePort. One disadvantage to the way Global Village wrote
- this software is that the TelePort can be set up either as a CTB
- device, or with serial port shadowing. It would be much better if
- it could be set to do either, and block the other method when one
- was in use. That way the user could use several different
- communications programs without having to worry about
- reconfiguring the TelePort software each time. This would not be a
- terribly difficult thing for Global Village to add; they simply
- have to add it to their list of things to do.
-
- One of the TelePort's main features is its support of MNP. When
- the TelePort is talking to another modem that also supports MNP 1
- through 4, you should have a reliable connection; no line noise
- will appear in all but the worst connections. This function,
- designed by Microcom, has both modems check the data that is being
- exchanged to be certain that no errors have come through the phone
- line. If an error is detected, the receiving modem will ask the
- sending modem to send the garbled information again. In addition,
- MNP 5 provides data compression, which can increase your
- "throughput," or the speed at which data travels over the line, as
- much as two times. This is similar to compressing data using a
- utility such as StuffIt or Compact Pro, but the compression and
- decompression are done by the communications device instead of
- using separate software in the computers at either end, without
- the user having to do anything special. The disadvantage of this
- method is that transferring already-compressed files, such as
- StuffIt archives, can occasionally decrease the speed if you have
- MNP turned on.
-
- The TelePort actually handles MNP a bit differently from most
- modems. Rather than implementing the MNP routines in firmware, or
- in the modem's chips, Global Village chose to handle it within the
- TelePort software. This would allow for future improvements in the
- compression technology, and for updates that would not require
- replacing the modem. Unfortunately, the current software does not
- handle MNP connections properly all the time, so Global Village is
- working hard to fix the software and release an update. The recent
- System 7 compatible release, version 1.06, improves the situation,
- but doesn't quite eliminate the problem. Users who do experience
- problems with the MNP function are advised by Global Village's
- technical support folks to turn off that feature in the TelePort
- control panel.
-
- [Do note that few, if any, of the online services support MNP.
- I've recently been dealing with finding UUCP mail servers, many of
- which use Telebit modems, and several people have said that they
- don't turn on MNP on those modems because it can cause trouble.
- Thus, although MNP is excellent if you know you will connect to
- other modems using MNP, don't assume that everyone uses it. -Adam]

- Faxing with the TelePort
- ------------------------
- The TelePort's fax capability is elegant and easy to use. If you
- purchase the fax version of the TelePort or purchase a fax upgrade
- later, you receive a TelePort/FAX file to join the TelePort
- control panel in your System Folder. This new file is a Chooser
- extension that lets you choose the TelePort as though it were a
- printer. This means that sending a fax is almost as simple as
- printing a document on your printer! When you have the
- TelePort/FAX selected in the Chooser, choose Print... from any
- application's File menu, and you'll get a simple dialog box that
- lets you type in a fax telephone number and the recipient's name
- (you can also manipulate a fax phone book, so you won't have to
- remember frequently-used fax numbers). Clicking "OK" causes your
- program to "print" the document to the TelePort's fax software,
- which then calls the receiving fax machine, and sends the fax.
- Mucking about with the Chooser can be a pain if you are sending a
- number of faxes and also printing frequently, so Global Village
- added a nice feature to simplify the process of switching. Merely
- hold down the option key when you choose Print... and you'll see
- the TelePort dialog box instead of the standard Print dialog box,
- even if you have another printer selected in the Chooser.
-
- Faxed documents that have been sent by the TelePort look much
- sharper and cleaner than regular faxes, because they are never
- "scanned" by an imperfect optical fax machine. And, since the
- TelePort software takes advantage of both Adobe Type Manager and
- TrueType, you can use outline fonts that will look good at any
- size.
-
- According to Global Village, future improvements to the
- TelePort/FAX software will include automatic group faxing (sending
- a single fax to a group of recipients at once), fax scheduling (so
- you can send an unattended fax late at night to save telephone
- charges), and improved phone-book handling.
-
- For early purchasers who have the 4800 bps FAX version of the
- TelePort instead of the newer 9600 bps version, a very inexpensive
- upgrade is available. Users should contact Global Village for the
- details.

- TelePort Conclusions
- --------------------
- John Sculley, in his keynote speech at the last San Francisco
- Macworld Expo, held up a TelePort, and announced that it was the
- most Mac-like Macintosh peripheral he'd ever seen. Because it
- takes advantage of a purely Macintosh way of communicating with
- the computer, it's particularly innovative. MacUser agrees with
- Mr. Sculley; the same week, they awarded the TelePort the 1990
- Editor's Choice Award for best communications product.
-
- While the TelePort has its imperfections, I must agree that it is
- the most innovative communications product recently introduced for
- the Macintosh. It's a very functional modem; the software seems to
- be very stable (it runs 24 hours a day on Memory Alpha BBS!); and
- it's very easy to set up and operate. If you are considering
- buying a modem for your Macintosh (SE or later; it will not work
- with a Plus or earlier), you should consider the TelePort.
