Description
Setting this attribute to TRUE requests that a TCP/IP provider enable the use of keep-alive packets on TCP connections. After the system detects that a connection was dropped, VISA returns a lost connection error code on subsequent I/O calls on the session. The time required for the system to detect that the connection was dropped is dependent on the system and is not settable.
