[Help-smalltalk] closing a socket when using NetServer.st

[Stephen]

Hi everyone,

I've got a script which when called, sends one line of text to a server 
port and then exits. The client and server scripts are both GST.

I decided to use the NetServer.st class for the server script, and I've 
based the server script on the example at 
http://sblinn.jottit.com/gnu_smalltalk_netclients-based_echo_server

The chat server example works fine with say netcat , i.e. nc 172.21.5.5 
8000. So then I press <Ctrl><C> to end the Netcat session and get the 
following dump at the server end....

'New session!'

optimized [] in NetClients.NetSession>>run
SystemExceptions.FileError(Signal)>>activateHandler:

My question is, how do I get the "server" script to terminate the 
session nicely when the client terminates.
My client script is closing the socket, and then the server script does 
a dump like the one above each time.

Thanks
Stephen
