Node.js nodejs如何将变量发送到tcpsocket

我想向client.write（）发送变量comm； 谢谢

client.write（comm“\n”、“binary”）；没关系，哈哈

var comm = process.argv[2];
var client = new net.Socket();
client.connect(PORT, HOST,function() {
    console.log('CONNECTED TO: ' + HOST + ':' + PORT);
    client.write('global.comm \n',"binary");
});
