(keitai-l) Serial Cable internet access adapter

I needs to figure out how to give my company's portable devices a
connection to the internet through an i-mode phone.  I'm imagining a
dongle cable from our product to the serial connector on the phone,
and using DoCoMo packet mode (DoPa) to wrap our UDP packets and thus
give our device a link to the internet.

Is this is possible?  Can anyone recommend an information source,
person, or company that could help me get this done?

TIA, Deane
