TCP.CONNECT.TIMEOUT= 30 | number of seconds

This parameter defines the length of time in seconds that a non-DTF interface (IBM Control Center, Connect:Direct® Browser User Interface, TELNET, port scanners etc) will be allowed to linger when an attempt is made to connect to the TCP.LISTEN port rather than the TCP.API.LISTEN port. Value can be from 5 seconds to 300 seconds.

The default value is 30.
