[Boost-users] [Asio] Cannot set port number on endpoint

Hi,

I'm new to Boost and am trying to write a command line networking tool. 
I am currently working in Windows XP SP2 using MS Visual Studio 2005. I 
use the default compiler. I have read a few tutorials and examples on 
using Asio, and thus wrote my app using that information, as well as 
information from the reference library. Currently the problem that I 
have is that I cannot set the port used by the endpoint to the value I 
want - 10540 -  it is always set to 11035. I'm not sure why this is, I 
cant find the number 11035 anywhere in the code or documentation so I am 
not sure where it comes from. I have tried to instantiate a new endpoint 
using the IPv4 address as a string and the port number as a short, and 
have also tried to construct a query that specifies the protocol, host 
name, service name (port number in this case) and the numeric_service flag.

In either case, when I debug, the port of the endpoint is always 11035, 
no matter what I set it to. I am able to connect to the endpoint, but 
not able to write data to it. I get a "File handle supplied is not valid 
error message". I presume the most likely reason for this is that the 
port 11035 is not open.

The machine that I am trying to connect to is running Red Hat EL4 Update 4.

I would appreciate any help in this matter.

Thank you,
Jonathan.
