Okay ik heb antwoord van Casio zelf:
"Thank you for your interest. Unfortunately a GPRS connection with E-115
istn't possible. As we know the Nokia 6610 has an integrated modem.
Generally there should be possible to stablish a connection via InfraRed but
with max. speed 9600bps.
If you want to connect your E-115 with a Nokia mobile phone there could be
some problems by stablishing a connection. Read the following lines too.
There is a patch available for Cassiopeia E-115. This patch alters the
software-controlling of the Infared-Port.
After the installation, it should be possible to establish a connection
between the Cassiopeia unit and a Nokia Cell-Phone (for example 8810 and
7110) via the Infrared-Port.

Installation notes:
1. Connect the Mobile device with the PC via the Dockingstation
2. Extract the Zip-File and install the software
3. During the installation progress, you will be asked to overwrite a
certain file (irsir.dll) on the Cassiopeia. Answer this dialogue with "yes".
4. Perform a reset on the Cassiopeia after the installation has finished
(this kind of reset is similar to a reboot, no data will be lost)."
Kortom: vrijwel onmogelijk, en als het al werkt max. 9600 kbps?
