2. Demonstrate the string length by entering 16 data characters. When
you enter the 16th data character, the module will transfer the string
of 15 characters to the read block transfer file in the data table where
you can display it. Do the following example where you will read
data from your ASCII device. Refer to the procedures in section
titled “Reading Data From your ASCII Device” (chapter 2), if
necessary.
