Currently I had successfully sent ringing tone to nokia handphone OTA by using a GSM MODEM. I tested it using hyperterminal and the AT commands I used:
However, I can't send the ringing tone to nokia handphones OTA by using a datacable connecting to a nokia 8250. The hyperterminal cannot seems to communicate with the 8250. But I have seen it working when using the software logo manager.
So May I know how can I let hyperterminal communicate with the nokia 8250 and can AT commands used in GSM MODEMs be used in NOKIA handphones for sending smart message purpose?
Thanks in advance. Your help is sincerely appreciated. =)
