Since R2021a

Syntax

writeline(v,data)

Description

writeline(v,data) writes the ASCII text data followed by the terminator to the VISA resource v. The function suspends MATLAB^® execution until the data and terminator are written.

Examples

Write ASCII Line to VISA Resource

Create a connection to a VISA resource. This example shows a connection to a device with the alias COM4 using the VISA-Serial interface.

v = visadev("COM4");
