convertir instruccion C a Delphi Lectoras SOYAL
hola amigos del foro esty trantando de ejecutar una libreria hecha en C .dll pero usando lenguaje Dlphi quisiera su ayuda para poder ejucutar ajunto la ayuda total del software pero en est momento por me gustaria saber como hacer estas asignacion:
Código:
// TxBfx[0] = 0xFF; // Destination Node Address
// TxBfx[1] = 0x12; // Node information
// TxBfx[2] = 0x02; // Read Command
// TxBfx[3] = 'R'; // Parameters
// nLen = 4;
la explicacion total de como usar la dll la adjunto ya que mi edea es simularla en delphi y apenas logre procesarla la opiare a este forum
Código:

// BOOL IsPortAvailable( int CommPort )
// In : Serial port number (0 ... n) for COM:1 ... COM:n+1
// Returns: If the port is available or not
//
////////////////////////////////////////////////////////////////////
// void* CreateSPort( void )
//
// Returns: If create successfully return the pointer of Item object that
// represents the communication object that is created. otherwise return NULL
// Effect: Use the method to create a objec for communication to a serial device
//
////////////////////////////////////////////////////////////////////
// BOOL DeleteSPort( void *pComm )
// Returns: Nonzero if successful; otherwise zero
// Effect: Delete the object created by CreateSPort()
//
////////////////////////////////////////////////////////////////////
// BOOL OpenSComm( void *pComm, int Port )
// In : Communication Object address, that create by CreateSPort
// Serial port number ( Ex: 0 for port COM1, 1 for port COM2 )
// Returns: Nonzero if the opening was successful
// Effect: Connect the communication object to serial port in 9600,N,8,1
//
////////////////////////////////////////////////////////////////////
// BOOL CloseSComm( void *pComm )
// In : Communication Object address, that create by CreateSPort
// Returns: Nonzero if the opening was successful

////////////////////////////////////////////////////////////////////
// BOOL ReadWriteSComm( void *pComm, BYTE* TxBfx, BYTE* RxBfx, WORD* pLen )
// In : Communication Object address, that create by CreateSPort
// TxBfx: Address of data block to transmit
// RxBfx: reserved memory block to receive data
// SendLength: number of bytes to transmit
// Returns: Nonzero if all bytes transmited and put the received bytes in *pLen
// Effect: Transmits *pLen bytes of data from TxBfx to the serial port,
// and receive the return data in RxBfx
//
////////////////////////////////////////////////////////////////////
// DWORD GetSCommStatus( void *pComm )
// In : Communication Object address, that create by CreateSPort
// Returns: Return unsigned long data of last ReadWriteSComm status

// BOOL ConfigSComm( void *pComm, int baud )
// In : Communication Object address, that create by CreateSPort
// Serial port speed
// Returns: Nonzero if all bytes transmited and put the received bytes in *pLen
