Perhaps I've found an old or out-of-date T10s User Guide (as· attached) on the Erricson web site, but I see nothing in there that even intimates that it will accept an external serial connection. Do you have any Erricson documentation to that effect?

Regards,

I've ever test Ericsson T10s with its cable with my PC. and I can send command "AT" and it reponse by sending "OK" back to hyper terminal. After that I use another mobile call the phone number and it response by sending "RING" back.

I suggest that I can use Microcontroller replace PC to do so.

Sorry I don't have any document.

Please remember that PC's support full duplex asynchronous serial communication, and natively, the PBASIC Stamp does not. You can add an external UART to gain that capability, but that's about it. If you want to go the external UART route, take a look at the Maxim MAX3100.
