Member Data Documentation

◆ audio_rx_log

int fax_modems_state_s::audio_rx_log

Audio logging file handle for received audio.

Referenced by fax_restart(), and t38_gateway_init().

◆ audio_tx_log

int fax_modems_state_s::audio_tx_log

Audio logging file handle for transmitted audio.

Referenced by fax_restart(), and t38_gateway_init().

◆ logging

logging_state_t fax_modems_state_s::logging

Error and flow logging control.

Referenced by fax_modems_get_logging_state().

◆ rx_handler

span_rx_handler_t* fax_modems_state_s::rx_handler

The current receive signal handler.

Referenced by faxtester_rx().

◆ rx_signal_present

int fax_modems_state_s::rx_signal_present

TRUE if a carrier is present. Otherwise FALSE.

Referenced by faxtester_rx().

◆ transmit_on_idle

int fax_modems_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.

Referenced by fax_set_transmit_on_idle(), faxtester_set_transmit_on_idle(), faxtester_tx(), t31_set_transmit_on_idle(), and t38_gateway_set_transmit_on_idle().

◆ tx_handler

span_tx_handler_t* fax_modems_state_s::tx_handler

The current transmit signal handler.

Referenced by faxtester_tx().

◆ use_tep

int fax_modems_state_s::use_tep

TRUE is talker echo protection should be sent for the image modems

Referenced by fax_set_tep_mode(), faxtester_set_tep_mode(), t31_set_tep_mode(), and t38_gateway_set_tep_mode().
