Inherits from I/O Session class.
| Long Name | Description |
|---|---|
| TCP/IP Settings:No Packet Delay | Specifies whether the Nagle algorithm is enabled. The Nagle algorithm is disabled when this property is TRUE (and vice versa). The Nagle algorithm improves network performance by buffering written data until a full-size packet can be sent. This property is TRUE by default in VISA to verify that writes get flushed immediately. Details |
| Message Based Settings:Suppress End Enable | Specifies whether to terminate a read operation due to an END condition. This property is relevant only in VISA Read and related operations. Details |
| Message Based Settings:File Append Enable | Specifies whether VISA Read To File appends or overwrites (truncates) when opening a file. If this property is set to TRUE, VISA Read To File appends when opening a file. If this property is set to FALSE, VISA Read To File�overwrites (truncates) when opening a file. The default is FALSE. Details |
| TCP/IP Settings:Computer Hostname | Returns the host name of the device. If no host name is available, this property returns an empty string. Details |
| TCP/IP Settings:Port Number | Returns the port number for a given TCPIP address. For a TCPIP SOCKET resource, this is a required part of the address/resource string. Details |
| Message Based Settings:IO Protocol | Specifies which protocol to use. In VXI, you can choose normal word serial or fast data channel. In GPIB, you can choose normal or high-speed HS-488 transfers. In serial, TCP/IP, or USB, you can choose normal transfers or 488.2-defined strings. In USBTMC, you can choose normal or vendor-specific transfers. The default is Normal. Details |
| TCP/IP Settings:Dot-Notation Address | Returns the TCPIP address of the device to which the session is connected. This string is formatted in dot notation. Details |
| TCP/IP Settings:Keep-Alive Packets | 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. Details |
| Message Based Settings:Termination Character | Specifies a character that, when read, causes a read operation to terminate. The termination character also must be enabled. This default is 0x0A (linefeed). Details |
| Message Based Settings:Termination Character Enable | Specifies whether a read operation terminates when it receives the termination character. The default is FALSE. Details |
| Message Based Settings:Send End Enable | Specifies whether to send an END indicator on the last byte of each write operation. This property is relevant only in VISA Write and related operations. The default is TRUE. Details |
