Serial com on Treo 600

[PalmOS]

Hi,

I've written a small apps which allow me to read GPS information from Holux
mouse connected to a Tungsten W.
Unfortunately the same won't work on my Treo 600. No errors returned but
TimeOut. Is there something special to do to make it works on Treo 600 ?

thank you very much in advance.


Sample of my code:

UInt16 OpenSerialPort ( UInt32 aSpeed )
{
 UInt16    lSerialID;

 Err    lError;
 UInt16  lParamSize;
 UInt32  lFlags = srmSettingsFlagBitsPerChar8 | srmSettingsFlagStopBits1;
 Int32  lCTSTimeOut = 1;


 lSerialID = 0;

 // check for ROM version
 FtrGet ( sysFtrCreator, sysFtrNumROMVersion, &gROMVersion );


  lError = SrmOpen ( serPortCradlePort, aSpeed, &lSerialID );

 if ( lError )  FrmAlert ( SerialOpenErrorAlert );

 else
 {
  printf ( "Serial Port opened\n" );

  // pas d'error
  lParamSize = sizeof (aSpeed);
  lError = SrmControl ( lSerialID, srmCtlSetBaudRate, &aSpeed,
&lParamSize );
  printf ( "srmCtlSetBaudRate : %d\n", lError );

  lParamSize = sizeof (lFlags);
  lError = SrmControl ( lSerialID, srmCtlSetFlags, &lFlags, &lParamSize );
  printf ( "srmCtlSetFlags : %d\n", lError );

  lParamSize = sizeof (lCTSTimeOut);
  lError = SrmControl ( lSerialID, srmCtlSetCtsTimeout, &lCTSTimeOut,
&lParamSize );
  printf ( "srmCtlSetCtsTimeout : %d\n", lError );
 }


   SysTaskDelay (50);

   return lSerialID;

}


//***** Main program

UInt16 aSerialPortID;
UInt32 lNbCar, lErrorCode;
char    lBuffer[250];


    aSerialPortID = OpenSerialPort ( 4800L );
    SerialReceiveCheck ( aSerialPortID, &lNbCar );
    printf ( "SerialReceiveCheck : %d\n", lNbCar );

    if ( lNbCar > 0 )
    {
        SrmReceive ( aSerialPortID, lBuffer, lNbCar, 10, &lErrorCode );
        printf ( "buffer : %s\n", lBuffer );
    }

    SrmReceiveFlush ( aSerialPortID );

//***** End of main program
