What do you mean by ping? Keepalive?

Is there any way for me to change the ping settings to lower than 30 secs? I already checked the documentation about open connections. There is the sever response timeout. I already set it to 5. I need to lower the ping time for the connections because I would use a recurring program for it and if the connection does not connects within 5-10 secs I need it to end quickly to restart the connection again.
