I have done this with a display terminal. When you change the display
file to dfrwrt(*no) each write of a display file record does not
complete until the data has been written to the display.  In my case I
retrieved the millisecond current time, wrote a bunch of display
records containing 24x80 lines of characters, then calculated how long
it all took.
