Hello all;

 

I seem to be having a problem writing to ttyO1.

Here is the really simple code and the result on the console:

 

Code:

 

var data

var serialPort, sp;

var serialPort = require("serialport").SerialPort;

var sp = new serialPort("/dev/ttyO1", { baudrate: 9600 });

 

sp.on("open",function(){

    console.log("Hello World the Comm Port is Open");

    

});

 

function sp_write(data){

    sp.write(data,function(err, results) {

            console.log('err ' + err + ' What happened? ' + results);

        });

}

 

togglepin();

 

 

function togglepin(){

 

    // High and low parts of the frame length (not counting checksum)

    sp_write("Hello Again):

    //sp_write(0x0);

    //sp_write(0x10);

}

 

 

And here is the console Output:

 

Error: Serialport not open. What happened? undefined

Hello World the Comm Port is Open

 

Anyone got any ideas ??

 

Bill
