Hi,

Forwarded reply from my colleague:

"I have had similar problems.

What I discovered talking to various mobile phone manufacturer tech.
support is, that there is two types of data support on mobile phones,

1.   Physical hardware modem, built into the phone. (which permits you to
talk to it as a modem, via an RS232 using AT... commands)
2.   "Soft Modem". Where the so called modem support is actually in a
software program running on the host machine.
     This provides the "PC" with the modem support, AT commands, etc. and
talks to the phone using a manufacturer "proprietary" command set and
protocol.

(This is something the manufacturers keep close to their chest, although
there are groups on the WEB that have reverse engineered various this
instruction set and protocol for Nokia and others.)

So, when Nokia say...

GSM data transmission
Supports 9600 bps via Nokia Cellular Data Suite.

...they mean "soft modem".   "


Regards,
Dan
