Hello,
There is a new document available describing the FIFO protocol of SER in detail. The document describes the basics of FIFO communication, how to write an application that will communicate with SER and it lists most of the commands available in SER and their syntax.
I have not integrated the document into SER docuementation yet, you can get preview from:
http://iptel.org/~janakj/fifo.pdf
Any feedback is appreciated.
Jan.
