From your circuit you have got gnd connected to pin 5
also if you can communicate to the phone using hyperterminal
then you need to connect a null modem between your pic and the phone or just swap Tx with Rx

Why don't you make it yourself?

[DragonBall_6]

I also think like that but is it very hard?
maybe I want to take a try.
Do you have the schematic or website?

Thank a lot.

Thank for the reply..Really thank.....

May I know in your circuit which part is to connect my handphone connector such as nokia 6100.
I'm not able to find the serial data cable in the market(malaysia) nowadays to connect my mobile phone. What i can find is the usb connector one not the serial port one.

Can I connect like this??: handphone-->handphone connector-->usb male-->usb female to female converter------>usb-serial adapter then i can connect to my PC.Is that possible and do i need any driver?????

Because as i know, to send data thru usb is very complicated so i need to find a way to send data using serial cable. it is much easy.

Pls advice...

Thank you very much>>>>

Firstly you need to find out if u'r fone is AT-capable most of valid fones have modem dlr3p cable will only work in 6110 series and 7110 series or compatible phones i believe 6100 is using POP-PORT and if u'r talking about USB connection either HOST or PERIPEHERAL mode you will be needing USB to TTL logic converter like those chips from maxim or FTDI because USB is LVDS "low voltage differential signaling" try to find out more about your phones POP-PORT if it sends out TTL and if it is AT-commands compatible and by the way you need to figure out if your phone is can handle TEXT or is PDU by defualt the formeris easier!!! if it is in PDU mode you wont be able to get a response from your phone you will need to be doing translation in your software!!!

PS.

The 7-pin in the ckt is directly pin to pin to 6110 or 7110 port i used an old headfone very cheap even the fone is cheap roughly 900 pesos or 20US$

Bro what do you mean "HACK VERSION" of firmware...

What part was hack?


Mabuhay!!

[leisryan]

original dlr3p has a propreitary signal which sets up the 6210 series and alike fone inorder to accept data from their PORT unlike older cables MBUS,FBUS etc!!! you can follow the link i posted recently above!!!
