void main_cdc_disable ( uint8_t  port)

Closes the communication port This is called by CDC interface when USB Host disable it.

References main_b_cdc_enable, and uart_close().

bool main_cdc_enable ( uint8_t  port)

Opens the communication port This is called by CDC interface when USB Host enable it.

Called by CDC interface Callback running when USB Host enable CDC interface.

Return values
trueif cdc startup is successfully done

References main_b_cdc_enable, and uart_open().

void main_cdc_set_dtr ( uint8_t  port,
bool  b_enable 
)

Save new DTR state to change led behavior. The DTR notify that the terminal have open or close the communication port.
