Socket transmit queue size successfully configured;

...

• Partially truncate any transmitted data but instead allows data from exactly one transmitted packet buffer to overflow the configured size since each datagram must be transmitted atomically (see section C-13-48 “NetSockfunction NetSock_TxData() / send() (TCP) NetSock_TxDataTo() / sendto() (UDP)”).

For steam sockets, size may be required to be configured prior to connecting (see section C-14-6 “NetTCPfunction NetTCP_ConnCfgTxWinSize()”).
