I am using SIM reader and an FTDI based rs232<->usb interface to create a serial connection to my SIM. So my computer can talk to the SIM! Now, I would like to do the same the other way around: to make my computer talk to the the phone so I can monitor and learn from the communication between them.
Any ideas on how to do this? Are there any designs or maybe even finished products that can do this?
Thanks in advance!
