MATLAB: Am I unable to clear the display of the Agilent 34410a multimeter using Instrument Control Toolbox 2.4.2 (R2007a)

Instrument Control Toolbox

I execute the following lines to clear the display on my multimeter:
v = visa('agilent','GPIB7::3::INSTR')
fopen(v)
fprintf(v,'disp:text:clear')
fclose(v)

This is the expected behavior. The DISPlay:TEXT:CLEar command for the Agilent 34410a does not blank the display, but clears custom text set with DISPlay:TEXT and returns to the (non-blank) default display. This default display may be DC Voltage or a similar measurement based on instrument settings. The following code displays "hello" for 5 seconds, then returns to the default display:
v = visa('agilent','GPIB7::3::INSTR')
fopen(v)
fprintf(v,'disp:text "hello" ')
pause(5)
fprintf(v,'disp:text:clear')
fclose(v)
