Developing a Fax Application

Transfer Mode 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.

Current Page Transmission Parameters 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.
