I have a small problem to connect my Nokia 6230 to the serial PC port, looking in internet i found a cable schematic of DKU-5. this is the address:
Here is the cable schematic but a i try to connect my 6230 by the pop-port and doesn't work. i used a Rx and Tx Fbus, when i try to send a AT command the phone doesn't respond. So i need really help to do this. I need to connect this cell phone via RS232 using the pop-port because i try to take control of the cell phone by a microcontroller.
If someone know how to connect correctly the Nokia 6230 via rs232
please let me know.
I'll appreciate your help
