Problem getting mode from kenwood ts-950

Hi

I use the dll's in .NET 

I have a thread containing : (the rig object is created in the same thread.)

 rig = HamlibInit(213);
 int result = Hamlib.HamlibOpen(rig,  <at> "COM11"); //just sets the rigport pathname to the comport

while (threadrunning)
{
   rig_errcode_e err;

   err=rig_get_mode(rig, vfo_t.RIG_VFO_A, ref mode, ref filter);
   Console.WriteLine(mode.ToString());
   Console.WriteLine(err.ToString());

   System.Threading.Thread.Sleep(1000);

   err = rig_get_mode(rig, vfo_t.RIG_VFO_B, ref mode, ref filter);
   Console.WriteLine(mode.ToString());
   Console.WriteLine(err.ToString());

   System.Threading.Thread.Sleep(1000);
}

It produces :

RIG_OK
RIG_MODE_CW
RIG_EPROTO
RIG_MODE_CW
RIG_EPROTO
RIG_MODE_CW
RIG_EPROTO
RIG_MODE_CW
RIG_EPROTO
RIG_MODE_LSB
RIG_OK
RIG_MODE_LSB
RIG_EPROTO
RIG_MODE_LSB
RIG_EPROTO
RIG_MODE_CW
RIG_OK
...

This is while my trx is in LSB on VFO A and in CW in VFO B
What is worse : the transceiver switches between VFO A and VFO B, I don't get it since I only use rig_get_mode !

Also in my Kenwood manual says RTS/CTS is used, but the caps structure is initialised with HANDSHAKE_NONE.

What is wrong with this trivial code ?
