- 1 minute(s) read
Specifies whether to use keep-alive packets on TCP connections. Setting this property to TRUE requests that a TCP/IP provider enable the use of keep-alive packets on TCP connections. After the system detects a dropped connection, VISA returns a lost connection error code on subsequent I/O calls on the session. The time required for the system to detect the dropped connection depends on the system and is not settable. The default is FALSE.
