I am now sending & receiving wireless Internet & Compuserve EMAIL via my Sharp
Zaurus model ZR-5800 and my Motorola flip cellular phone. This means there is
no hardwired cable connection to a phone outlet & one can get email messages
as easy as

A. PARTS:
1. Motorola Model FD9HLD838AG old style flip phone (the alpha numeric version
   of their popular 550).
2. Motorola Power Cellect 14.4 Cellular PCMCIA card.
3. Motorola cable #610406070001. This goes between the PCMCIA card in the
   Zaurus to the cellular phone. It came with the modem.

B. ZAURUS MODEM SCRIPT: AT&F1J2S7=100S10=100

C. SETUP: Set the Zaurus's Modem setup to 2400 Baud (higher may work), PC
Card, check the Hardware Flow Control Box and set the volume to 2. Now just
sign on to Compuserve your regular way and you'll be able to get messages from
all over the world.

D. BATTERY USAGE: My tests were done with used-for-a-week, but good, AA's in
the Zaurus and a 1/2 spent Motorola large NiCad battery. No AC adapters were
used. Fresh batteries should be probably used for good results, though.

Good luck.

Both MegaHertz & Motorola have gotten good forum reports. I use the MOT 14.4
Power (discontinued) as I have a MOT flip phone & it works flawlessly. If you
can find one get it as they were selling out of them for around $50 at Staples
a few months ago. See the library file ZCELMAIL.TXT on my setup.

MOT replaced mine with a 28.8 one & I imagine it eats batteries so an AC
adapter will be needed. I get good battery performance out of mine but don't
use it that much as I'm a sidecar user most of the time. A 100 bucks + cable
is probably what you'll spend.

Speed is not important when used with a cellular as it is only around 2400, I
think, anyway. The slower the better is probably good due to the lower battery
drain do to fewer transistors and components.

Good luck.        --JHC

Robert:

I just purchased a used MOT Power 14.4 that can used with MOT flip cell
phones.  Unlike Jim, however, (who I think lives in LA), I am NOT getting
flawless performance in New York and along the east coast. First of all, his
modem string posted in the library would not work in New York. And, second, I
have yet to find a way to address the PIN number issue.

In NY, Nynex uses the newer E2 type cell phones that automatically generate
the PIN number.  However, when roaming, one must manually insert the PIN.
Since the Z and Modem "take over" the cell phone, I can find no way to insert
this PIN manually when outside NYC.  As a result I could not use the Z
wireless configuration on a trip last week.  I will be trying to work this out
with MOT this week but if I can't make it work reliably I'll make you a good
deal on wireless modem.

I copied it from the Sharp forum & it is manufactured my Motorola. Check with

Jim -- I use a Motorola Black Box3032A with a SKN4635A cable.  I can literally
send a fax as I walk down the street using a Motrola MicroTac Elite
phone.  It works very well. I got the toys from my Cell Phone supplier.

Thanks for the help!  By the way, the correct part number is S 3027A (I called
Motorola).  I contacted Bell Atlantic NYNEX here in Boston and the price is
$155.00.  The big question  - i it better to buy a PCMCIA cellular card, or
this portable cellular connect interface?  The decision would be easy if the
battery performance was substantially better using the black box.  Any
comments/experience? Again, thanks for all your help.

The "black box" draws nothing from the Wizard's batteries - it has its own 9
volt system.  However, the sidecar 2400 CE-FM4 draws bigtime on the Wizard's
two AAA cells, severely cutting down operating time from the estimates given
without a modem.

If the 28.8 card modem is cellular compatible (many are not) I would go with
that route.  If it is not cellular ready, then you would need it PLUS the
"black box".  I am not sure if the Zaurus can use the PCMCIA modem cards,
cellular ready or not.  JHC, the SysOP here would know about that.  IF the
Zaurus can use the card modem, and IF the card modem is listed as cellular
ready and doesn't cost much more than the "black box" I would spring for the
faster speed of the card.  2400 is dreadfully slow for Web Browsing!!  But is
DOES work with the "black box" and an ASCII Unix browser program called LYNX
which is on many university computers and some lnternet providers, like
Libertynet in Philadelphia, PA.  So I can not only get e-mail and send e-mail
on CompuServe with the black box, CE-FM4, and send faxes from anywhere, but do
a worldwide search on Yahoo or Lycos or any other search engine on WWW via my
cellular flip phone!  Amazing stuff!  Especially for a 2400 baud modem!!

But even the CE-FM4 sidecar eats batteries by the dozen if you are on line --
even landline phones -- a lot.  Just keep a pocketfull handy!  The Wizard
alone gets far better gas mileage than the Wizard with modem.  I imagine that
if the PCMCIA modem cards work with the Zaurus, they would also shorten life,
unless they have built in Lithium batteries, like the PCMCIA Pen Cell card I
have in my Wizard.  It draws nothing from the Wizard batteries.

        Lots of IF clauses here,but I hope this is helpful.

Bob,
I used the S3027 (Black Box)/Flip phone combo for sending faxes with my Z1.
You can expect the same amount of online time with the combo as with landline.
Each piece has its own power supply.  I have two S3027 willing to part with
them for $75 each.

Copies from the IBM ThinkPad forum about cellular PCMCIA modems. I don't know
whether an Apex is compatible but the other stuff was interesting to me.

---------------------------cut here-------------------------------------

Your problem lies with your IBM PCMCIA Modem.  Most likely the modem contains
NO cellular enhancements and/or protocols. In order to get speed and
reliability over cellular you need to invest in a cellular capable modem.
Sorry for the bad news :-(

My recommendation:  Apex Data's Mobile Plus.  It is a V.34 28.8/14.4 (landline
data-fax modem) Over cellular you should realistically achieve 9.6kbps speed,
however, you will be limited at times because your cellular phone only puts
out a maximum of 600 milliwatts power..."an Ant talking to an Elephant
syndrome".  The Apex MobilePlus comes equipped with an RJ11 cable which will
plug into your Cellular Connection Data Interface.  Note: Cellular
protocols/enhancements compensate for all the idiosyncracies that occur over
the air, i.e, noise on the channel, cellular handoffs, to name a few.  A
landline based modem cannot compensate for these idiosyncracies over the
airlink, therefore you either (1) connect unreliably at a very low speed or (2)
never connect.

I would also recommend checking to see if your cellular carrier offers a modem
pool which should match the TX-Cel enhancement built into the Apex Data modem.
Many carriers now offer modem pool service (some offer free of charge for the
service - you still pay for cellular connect times remember).  These modem
pools are accessed typically by placing *3282 in front of your host modem's
phone number in your software's setup screen.

To read more about the Apex modem, go to their web site at:
http://www.apexdata.com or call 1-800-841-apex

I personally use this modem with my motorola flip and my laptop...use with
compuserve and other software packages.  Direct connect cables  (no need for
an interface box) are made for a variety of portable phones on the
market...typically run around $60...modem is around $200-250 range.  One last
note: if you use the apex modem with your cellular connector, you may have to
adjust your modem string in Compuserve CIM.  Call Apex for help on this or
your cellular carrier's data help desk if they have one.

No, I don't work for Apex.
