Detailed Description

T.31 descriptor. This defines the working state for a single instance of a T.31 FAX modem.

Member Data Documentation

int t31_state_s::dled

TRUE if DLE prefix just used

span_tx_handler_t* t31_state_s::next_tx_handler

The transmit signal handler to be used when the current one has finished sending.

span_rx_handler_t* t31_state_s::rx_handler

The current receive signal handler

int t31_state_s::transmit_on_idle

If TRUE, transmit silence when there is nothing else to transmit. If FALSE return only the actual generated audio. Note that this only affects untimed silences. Timed silences (e.g. the 75ms silence between V.21 and a high speed modem) will alway be transmitted as silent audio.

span_tx_handler_t* t31_state_s::tx_handler

The current transmit signal handler
