Who can help me with : Serial Nokia FBus to AT Phonebook converter and vice versa

Hello all,
For special project i need a serial 115200 baud Nokia Fbus to AT command converter with PIC (or something else).
It has to do the following ;
a Fbus command looking for phonebook entries has to be converted to phonebook AT-command (AT+CPBF, AT+CPBR)
the phonebook results of the AT-command has to be converted back to the Fbus device.
I think it has to be done with 2 way conversion,
Fbus -> AT and,
AT -> Fbus

Anyone know, seen this ?

any suggestions ?
Or somebody ever did Fbus to AT conversion ?

Perhaps one of us is confused? - I'm not sure which.

Isn't FBus a hardware connection (sort of like RS232), where as AT is a command structure used for modems - as far as I'm aware FBus already accepts AT commands.

What exactly are you trying to do?.

Hello Nigel,

I try to explain,

I have a device which has a hardware FBus, this i like a RS232 at 115200 baud. This device only can send and receive
fbus protocol. This device normaly is cable connected with old Nokia phones which only understand fbus protocol.
The phone info it can handle is SMS, out- incoming calls and phonebook.

What i want to do, is to connect newer phones which still have the availability of RS232 but only understand the
AT-modem commands.

So, if the Fbus device gives the command "retrieve phonebook" then a converter has to translate it into At-modem command for the newer phones. The new phone gives the phone book info, and this has to be translated back a fbus string, so that device can understand it.

Technicaly it can be done, only how to do this. Maybe somebody did do this before.

Program a micro-controller to do the conversion, a quick google found this near the top of the list:
