Tanks for the answer mr. Noordhuis, it is effectively as string that i send wich is at the base an array of hex values eg:
//===================================== var mCmd = new Array(34); mCmd[0] = 0x46; mCmd[1] = 0x49; ... for (i = 0; i < 34; i++) { sFinsCmdRead= sFinsCmdRead+ String.fromCharCode(mCmd[i]); } //===================================== The question is how do i use buffer ? Is that as simples as : //===================================== buf = new Buffer(str.length); for (var i = 0; i < str.length ; i++) { buf[i] = 0x00+i;} client.write(buf); //===================================== I will try tomorow if it is the case. What do you think about if using node.js is the best way to achieve my purpose ? Tell me if i'm not clear.
