My problem is to figure out how to use a Motorola E680 cellphone, which
runs Trolltech Linux, and can function as a dialup USB modem, using
Windows, to provide wireless access to the Internet, can be used as a
modem with a laptop running Linux (in this case Mepis Debian 3.3, but
that doesn't seem to matter). I have tried kppp and wvdial to no avail.

What does work is to boot the laptop under Windows, and run a
Motorola-supplied program called GPRSManager which issues dialup
commands to the phone creating what I presume is a ppp connection. That
works fine. I can browse, send and receive email, etc. (However I
haven't figured out yet how to send email from the phone or reply to
messages received. I can receive email on the phone at
5122995...@tmomail.net, but want to set up a mailbox that can send and
receive email.)

It was suggested that I send an initialization string

AT+cgdcont=1,"IP",:internet2.voicestream.com"

but this and variations on it using kppp or wvdial just return ERROR.

I can issue just the dialout number using

ATDT*99# but get NO DIALTONE and
ATD*99# but get NO CARRIER

using either kppp or wvdial.

Incidentally, on wvdial I had to insert a line in the /etc/wvdial.conf
file

Stupid mode = yes

and set the Username and Password to " " (blank) to get it to run.

I ran the strings command on the GPRSManager.exe file and examined the
(ASCII text) driver files for the Windows programs, but none of them
seem to contain anything that would issue anything resembling the above
suggested initialization command. Apparently some initialization
command is needed to set up the dialing of the number.

It would be nice to be able to get a computer running Linux to talk to
a phone running Linux. Of course, it would be even better if the phone
were a router rather than a dialup modem, but we can all join in urging
the cellphone manufacturers to come out with a product like that.

If anyone has any solutions, or can suggest other groups to post this
to, please email them to jroland at linux-migration.net.
