iX Talk

Hello, I have modified the sample program by Ron to send characters out of the COM port, but some of the chars get altered. It seems that the characters having the MSB set to 1 are converted to 3F regardless of their value.

The code I wrote is reported below, the commented lines show the actual value sent out by the serial port, caught with a serial sniffer. I am using iX 2.0 SP1 2.01.463.0, PC target.

Am I doing the wrong way to initialize the strings?

Thanks,
Federico

//OUTPUT ON THE COM PORT: 07 3F 42 52 54 01 10 00 3F
}
}
}

Problem found. It was due to the Unicode string encoding. I have changed the code to use the SerialPort.Write (Byte[], Int32, Int32) overload and now it works fine.
