Hello all, I would do a sim-emulator software that runs on my PC. First thing to do is a an interface to connect my PC with sim slot phone. So I am using this simple interface : I took a CP2102 module, see this page for example http://esaid.free.fr/Cdotnet/USB_serial.htm, then I have put a diode between TXD and RXD, then I have connected RXD to I/O of phone sim slot, DSR of CP2102 module to RESET of phone sim slot and connected the two grounds.          __________                                                       |         |________   TXD                               +5V------|         |     |                                        DP------|  CP2102 |___ \/__   RXD   -------  I/O phone sim slot  DM------|         |                                              GND-----|         |---------  DSR   ------- RESET phone sim slot          |         |                                                      |_________|--------   GND   ------- GND  phone sim slot I have tested this interface with a phone , I can detect reset from phone then I send this ATR: 3B 16 95 D0 01 7B BD 0D 00 ( this is the ATR I can read form a real sim card with a phoenix reader), but I don't have any response from phone. Any help is appreciated, thanks.
