Using AT commands by FBUS line...Help please

[D_robles0]

Hi all,

I am developing a hardware as a University project based on a PIC microcontroller, where I control the cell phone using AT commands as a ASCII characters. I proved the phone using Hyperterminal and introducing the commands, but the connection is by USB cable DKU2. So with this configuration te cell phone response perfect.

In internet are a lot information of Fbus as a serial connection to Nokia Cell phone and schematics to connect the phone using a MAX232, so my question is posible to send At commands using the serial data cable through FBUS line, because I read some documents that this isn't posible a other where it is.

Please help anyone how have knowledge about this.
I will appreciate your help.
