Works on Windows but timeout on linux

Question

I have a problem with the code below. It perfectly works under Windows, but I am getting a timeout under Linux. I am not sure why. Any ideas?
One more thing: Under Liunx It fails when I am testing it using port 1935. However, if I test it with port 110, it works. On Windows it works with both ports (110 & 1935).
Thanks you!

[ Don't use PrintWriter or PrintStream|http://forums.sun.com/thread.jspa?messageID=10642137#10642137]
outToServer.println((char)13);You should flush() the outputstream after writing, before you do a subsequent read on the socket's inputstream.
catch(IOException e) {
if (status == 1){
ErrorDescription = ErrorDescription+"ERRTEL01 Error in TELNETMonitor Thread: "+e.getMessage();
}else{
ErrorDescription = "ERRTEL01 Error in TELNETMonitor Thread: "+e.getMessage();
status = 1;
finally {
theSocket.close();
catch(UnknownHostException e) {
if (status == 1){
ErrorDescription = ErrorDescription+"ERRTEL03 Error in TELNETMonitor Thread (INVALID HOST): "+e.getMessage();
}else{
ErrorDescription = "ERRTEL03 Error in TELNETMonitor Thread (INVALID HOST): "+e.getMessage();
status = 1;
catch(ConnectException e) {
if (status == 1){
ErrorDescription = ErrorDescription+"ERRTEL04 Error in TELNETMonitor Thread (THE HOST DOESN'T RUN A SERVER ON THE SPECIFIED PORT): "+e.getMessage();
}else{
ErrorDescription = "ERRTEL04 Error in TELNETMonitor Thread (THE HOST DOESN'T RUN A SERVER ON THE SPECIFIED PORT): "+e.getMessage();
status = 1;
catch(IOException e) {
if (status == 1){
ErrorDescription = ErrorDescription+"ERRTEL01 Error in TELNETMonitor Thread: "+e.getMessage();
}else{
ErrorDescription = "ERRTEL01 Error in TELNETMonitor Thread: "+e.getMessage();
status = 1;
C'mon, Gustavo, you can have cleaner exception handling than that!
