The HiSLIP data is sent to the device using the "fire and forget" method with immediate
return. Opposed to VXI-11, where each operation is blocked until a VXI-11 device
handshake returns. Thus, a successful return of a VISA operation such as
viWrite()
does not guarantee that the sensor has finished (or even started) executing the
requested command. It just indicates that the command has been delivered to the
TCP/IP buffers.

Socket Communication
An alternative way for remote control of the software is to establish a simple TCP/IP
connection to the device using the standard network drivers of your operating system.
The so-called "socket" on Linux, "winsock" on Windows. The socket communication,
also referred to as "raw Ethernet communication", does not necessarily require a VISA
installation on the remote controller side.
Socket connections are established on a specially defined port. The socket address is
a combination of the IP address or hostname of the sensor and the number of the port
configured for remote control. The power sensors use port number 5025 for this pur-
pose.
