fbus commands

I'm going to interface a PIC with nokia 3310.

Can anybody tell me whats the relationship between FBUS & AT Commands?

There's another thing called PDU & Text format I'm confused with those words.

Thanks

AT Commands are ASCII codes.

Thanks mate I understood little bit.

I have some problems.Now phones like 3310 are not available.What are the other phones supporting FBUS which is commonly available?

The other problem is when I send a sample frame (get H/W & S/W version) to phone the phone will reply with two frames.

First frame is the acknowledge & the other is the data frame requested by us.

I want to know whats the time interval between these two frames?
 

Search the forum to find out more about phones supporting FBUS. There has been a lot of discussion on this topic.
