j2me cellphone external communication

[xera]

Hello Guru's,

From my cellphone, I need to communicate with an external microprocessor...

Does anyone know if there's a phone + cable with which you can accomplish this seemingly formidable task?

Also, do you know if it's possible to do this in java or c/c++?

Are you making the other device? Or is it something that is ready and you need to connect them?

The other device has already been made - at the moment it connects to the pc via the rs232 port. It's connected by 3 wires, tx, rx and GND.

So what I need to do is basically put the cellphone in the place of the pc, then read the data using a custom made program on the phone. Any Ideas?!

Thanks in advance
