The serial port has worked before it pops up randomly, I think I just need to clean them I was informed that serialport = read Beyond that the code won’t work because feof wants a read, but serialport does the reading apparently and when adding a read it still won’t work ...

An example code for virtual serial port communication with MATLAB Instrument Control Toolbox and the VISA interface: v=visa('agilent','ASRL4::INSTR'); fopen(v); fprintf(v,'abc'); fwrite(v, [97 98 99]); fclose(v); % clean up ...
A connected serial port object has a Status property value of open. An error is returned if you attempt a read or write operation while the object is not connected to the device. You can connect only one serial port object to a given serial port. Examples This example creates the serial ...
