| Public Attributes | |
| int | bit_rate | 
| The bit rate of the modem. Valid values are 4800, 7200 and 9600. | |
| get_bit_func_t | get_bit | 
| The callback function used to get the next bit to be transmitted. | |
| void * | get_bit_user_data | 
| A user specified opaque pointer passed to the get_bit function. | |
| modem_status_func_t | status_handler | 
| The callback function used to report modem status changes. | |
| void * | status_user_data | 
| A user specified opaque pointer passed to the status function. | |
| float | base_gain | 
| Gain required to achieve the specified output power, not allowing for the size of the current constellation. | |
| float | gain | 
| Gain required to achieve the specified output power, allowing for the size of the current constellation. | |
| complexf_t | rrc_filter [2 *9] | 
| The root raised cosine (RRC) pulse shaping filter buffer. | |
| int | rrc_filter_step | 
| Current offset into the RRC pulse shaping filter buffer. | |
| uint32_t | scramble_reg | 
| The register for the data scrambler. | |
| uint8_t | training_scramble_reg | 
| The register for the training scrambler. | |
| int | in_training | 
| TRUE if transmitting the training sequence, or shutting down transmission. FALSE if transmitting user data. | |
| int | training_step | 
| A counter used to track progress through sending the training sequence. | |
| int | training_offset | 
| An offset value into the table of training parameters, used to match the training pattern to the bit rate. | |
| uint32_t | carrier_phase | 
| The current phase of the carrier (i.e. the DDS parameter). | |
| int32_t | carrier_phase_rate | 
| The update rate for the phase of the carrier (i.e. the DDS increment). | |
| int | baud_phase | 
| The current fractional phase of the baud timing. | |
| int | constellation_state | 
| The code number for the current position in the constellation. | |
| get_bit_func_t | current_get_bit | 
| The get_bit function in use at any instant. | |
| logging_state_t | logging | 
| Error and flow logging control. | |
