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 "No one could make a greater mistake than he who did nothing because he could do only a little."
