port_flow_control_user() function

* Function rfc_port_closed * Description The function is called when port is released based on the * event received from the lower layer, typically L2CAP * connection down, DISC, or DM frame. * Returns void

* Function rfc_port_timer_start * Description Start RFC Timer

* Function port_rfc_closed * Description This function when RFCOMM side of port is closed

* Function rfc_port_timer_stop * Description Stop RFC Timer

* Function port_flow_control_peer * Description Send flow control messages to the peer for both enabling * and disabling flow control, for both credit-based and * TS 07.10 flow control mechanisms. * Returns nothing

* Function rfc_port_sm_execute * Description This function sends port events through the state * machine. * Returns void

* Function port_release_port * Description Release port infor control block. * Returns Pointer to the PORT or NULL if not found

* Function port_get_signal_changes * Description Check modem signals that has been changed * Returns event mask to be returned to the application

* Function port_start_control * Description This function is called in the BTU_TASK context to * send control information * Returns void

* Function port_rfc_send_tx_data * Description This function is when forward data can be sent to the peer

* Function port_start_close * Description This function is called in the BTU_TASK context to * release DLC * Returns void

* Function port_set_defaults * Description Set defualt port parameters

* Function port_select_mtu * Description Select MTU which will best serve connection from our * point of view. * If our device is 1.2 or lower we calculate how many DH5s * fit into 1 RFCOMM buffer.

* Function port_write * Description This function when a data packet is received from the apper * layer task. * Parameters: p_port - pointer to address of port control block * p_buf - pointer to address of buffer with data,

* Function port_get_credits * Description Set initial values for credits. * Adjust max number of rx credits based on negotiated MTU. * Check max allowed num of bytes, max allowed num buffers, * should be less then 255

* Function rfc_port_timer_free * Description Stop and free RFC Timer

* Function rfc_inc_credit * Description The function is called when a credit is received in a UIH * frame. It increments the TX credit count, and if data * flow had halted, it restarts it. * Returns void

* Function rfc_dec_credit * Description The function is called when a UIH frame of user data is * sent. It decrements the credit count. If credit count * Reaches zero, peer_fc is set. * Returns void
