4.4. Setting the Initial State of a Fax Channel

Set the initial state of the fax channel using fx_initstat( ). Following T.30 protocol, the caller station is initially set to be the transmitter (DF_TX) of a fax and the called station is initially set to be the receiver (DF_RX) of a fax.

Use this function once before issuing the first send or receive function of a fax session. Fax session refers to the completion of a fax call from Phase A through Phase E, as defined by the T.30 protocol.
