So did a system print and came back with an error,

System.setDebugMask(9);
var socket_GlobalRS232;
var buffer_GlobalRS232 = "";
var CR_GlobalRS232 = "\x0D";
function onSocketConnect() {
}
function onSocketData() {
var temp,first;
buffer_GlobalRS232+=socket_GlobalRS232.read();
first = buffer_GlobalRS232.indexOf(CR_GlobalRS232);
while (first >= 0) {
temp = buffer_GlobalRS232.substring(0, first);
buffer_GlobalRS232 = buffer_GlobalRS232.substring(first + 1);
notifyMessageReceived(temp);
first = buffer_GlobalRS232.indexOf(CR_GlobalRS232);
}}
function onSocketIOError(e)
{
System.print("sock IO Error error:" + e);
}
function notifyMessageReceived(message) {
System.print("Received:");
System.print(message);
}
function closeSocket() {
if (socket_GlobalRS232) {
if (socket_GlobalRS232.connected) socket_GlobalRS232.close;
socket_GlobalRS232 = null;
}}
function resetSocket() {
closeSocket();
socket_GlobalRS232 = new TCPSocket(false);
buffer_GlobalRS232 = "";
socket_GlobalRS232.onConnect = onSocketConnect;
socket_GlobalRS232.onData = onSocketData;
socket_GlobalRS232.onIOError = onSocketIOError;
}
function GlobalRS232(command) {
if (socket_GlobalRS232) socket_GlobalRS232.write(command + CR_GlobalRS232);
}
resetSocket();
socket_GlobalRS232.connect("192.168.1.6",4999,10000);

error is with line;

if (socket_GlobalRS232) socket_GlobalRS232.write(command + CR_GlobalRS232);

hard to read the entire error but says "socket not ready" offending line is pointing to the one listed above.
