List of all members.

Public Attributes |
|
int | iaf |
| | Internet Aware FAX mode bit mask.
|
|
int | ms_per_tx_chunk |
| | Required time between T.38 transmissions, in ms.
|
|
int | chunking_modes |
| | Bit fields controlling the way data is packed into chunked for transmission.
|
|
t38_core_state_t | t38 |
| | Core T.38 IFP support.
|
|
int | timed_step |
| | The current transmit step being timed.
|
|
int | rx_data_missing |
| | TRUE is there has been some T.38 data missed.
|
|
int | octets_per_data_packet |
| | The number of octets to send in each image packet (non-ECM or ECM) at the current rate and the current specified packet interval.
|
|
hdlc_tx_state_t | hdlc_tx_term |
| | An HDLC context used when sending HDLC messages to the terminal port (ECM mode support).
|
|
hdlc_rx_state_t | hdlc_rx_term |
| | An HDLC context used when receiving HDLC messages from the terminal port. (ECM mode support).
|
|
struct { |
| uint8_t buf [T31_T38_MAX_HDLC_LEN] |
| int len |
| } | hdlc_rx |
|
struct { |
| int extra_bits |
| | The number of extra bits in a fully stuffed version of the contents of the HDLC transmit buffer. This is needed to accurately estimate the playout time for this frame, through an analogue modem.
|
| } | hdlc_tx |
|
int | ecm_mode |
| | TRUE if we are using ECM mode. This is used to select HDLC faking, necessary with clunky class 1 modems.
|
|
int | non_ecm_trailer_bytes |
| | Counter for trailing non-ECM bytes, used to flush out the far end's modem.
|
|
int | next_tx_indicator |
| | The next queued tramsit indicator.
|
|
int | current_tx_data_type |
| | The current T.38 data type being transmitted.
|
|
int | current_rx_type |
| | The current operating mode of the receiver.
|
|
int | current_tx_type |
| | The current operating mode of the transmitter.
|
|
int | tx_bit_rate |
| | Current transmission bit rate.
|
|
int32_t | samples |
| | A "sample" count, used to time events.
|
|
int32_t | next_tx_samples |
| | The value for samples at the next transmission point.
|
|
int32_t | timeout_rx_samples |
| | The current receive timeout.
