Unit blcksock  Class TTCPBlockSocket

Then send and receive byte arrays using :

Public 	function SendBuffer(Buffer: TMemory; Length: Integer): Integer;
override;
Public 	function RecvBuffer(Buffer: TMemory; Len: Integer): Integer;
override;

var
 Tx_buffer : array[0..n] of byte;

SentN := SendBuffer(@Tx_Buffer,NumBytes);
