If ur cable also uses MBUS pin then it is a dual cable which supports both FBUS and MBUS This cable can be used as it is to PC side But when u r connecting it to microcontroller u have to convert the RS232 signals to TTL so u will need to put a MAX232 in betwn cable and Micro.Also u will need to connect DTR to +12V and RTS to -12V (which u can find on MAX232) But u can avoid all this by cutting the DB9 header female and put ur own female with no electronics. With this scheme u CANNOT connect to PC but u can connect to micro and avoid the DTR and RTS connection which is what I have done. So now u can put a MAX232 anyway on ur board for sniffing comm betwn micro and phone,becos both r on TTL (remembr the 5v to 3v though) the PC is just a watch terminal now. u can write a small progrm to send 55hex 128 times to phone followed by get version frame. and see what phone responds. check the tutorial again | |||

Abicash I am Clear about whatever you are saying but now i want to check connecting my mobile with the hyperterminal. for that what i should do since iam not getting any output from hyperterminal.

you cannot do that on hyperterm because u need to send some special hex codes like 1Ehex which doesnt have equivalent ASCII value(so u cannot enter via keyboard) u can enter '0'(zero) via keybord which is ASCII 0x30 (30hex)..so u see its highly impossible to send a train of codes which do not have ASCII equivalent,unless of course u send the whole frame which is highly improbable. Instead do the thing i mentioned previously Or use some simulation s/w like proteus which has a virtual terminal window |
