[XBoard-devel] TCP connection (expiry?) with ICS

[Svetlana Tkachenko]

I leave xboard open and connected to Internet chess server (ICS). After a 
while, because of what I think is it not sending any data to server, the 
connection dies. Due to the way TCP/IP works, the fact that the connection died 
is only known to server in some 20-30 minutes.

Is there a way to make xboard do something -- such as, if my understanding 
above is correct, send some dummy messages to server every few minutes -- so 
that I don't encounter the above issue, and can leave xboard connected to an 
ICS for days?
