Developing a Fax Application

November 2009

90

The application normally keeps track of its own 

operation mode (transmitting or receiving), but it can also use the 
LINE_DCS

 (see Volume 4, Fax Processing, Bfv API Reference Manual) 

macro to get this information.

The application can use 

the LINE_DCS macro to access information about the currently 

transmitting page; this information might change between pages. 

The information includes the bit rate, scan time, ECM mode, 

compression format, resolution, and width. The values for the first 

page are available after the BfvFaxWaitForTraining function has 

returned. Each time renegotiation or retraining occurs, the Bfv API 

updates the values available from the LINE_DCS macro.
