USB Host Shield 2.0 - How to enable DTR and RTS ?

hi,

i try receive data usb ftdi device (which push data every 10 secondes) display data in arduino monitor.
the problem (i think) have enable dtr , rts usb host shield 2.0, don't know how it.

usb configuration need:

baudrate: 115200
flow control: xon
dtr , rts on
capture local echo

can me please ?
i'm using arduino uno + usb host shield 2.0.

my code:

code: [select]


#include <sd.h>
#include <adk.h>
#include <cdcftdi.h>
//#include <usbhub.h>
#include "pgmstrings.h"

class ftdiasync : public ftdiasyncoper
{
public:
  virtual uint8_t oninit(ftdi *pftdi);
};

uint8_t ftdiasync::oninit(ftdi *pftdi)
{
  uint8_t rcode = 0;

  rcode = pftdi->setbaudrate(115200);

  if (rcode)
  {
    errormessage<uint8_t>(pstr("setbaudrate"), rcode);
    return rcode;
  }
  rcode = pftdi->setflowcontrol(ftdi_sio_disable_flow_ctrl, ftdi_sio_xon_xoff_hs);
  if (rcode)
    errormessage<uint8_t>(pstr("setflowcontrol"), rcode);

  return rcode;
}

int led = 13;
usb usb;
//usbhub hub1(&usb);
ftdiasync        ftdiasync;
ftdi             ftdi(&usb, &ftdiasync);
uint32_t next_time;

// setup routine runs once when press reset:
void setup() {             
  // initialize digital pin output.
  pinmode(led, output);
  // open serial communications , wait port open:
  serial.begin(115200);
  //for usb
  if (usb.init() == -1) {
    serial.println("ko: osc did not start.");
  }
  else {
    serial.println("ok: osc start.");
  }

  delay( 2000 );

  next_time = millis() + 5000;
  //end usb
}

// loop routine runs on , on again forever:
void loop() {
  usb.task();
 
  if( usb.getusbtaskstate() == usb_state_running )
  {
    digitalwrite(led, high);
    uint8_t  rcode;
    uint8_t  buf[64];

    (uint8_t i=0; i<64; i++)
      buf[i] = 0;

    uint16_t rcvd = 64;
    rcode = ftdi.rcvdata(&rcvd, buf);
    serial.println(rcvd);
    if (rcode && rcode != hrnak)
      errormessage<uint8_t>(pstr("ret"), rcode);

    // device reserves first 2 bytes of data
    //   to contain current values of modem , line status registers.
    if (rcvd > 2)
      serial.print((char*)(buf+2));

    delay(10);
    digitalwrite(led, low);
  }
}


thank in advance.
