Generic Device Driver
Checking the Control Commands

To check whether the definitions are actually supplying the required command strings for instrument control, enable the Demo mode. The device driver now sends all formatted character strings of a command to the Audit window of the corresponding timebase. Non-printable characters are displayed as hexadecimal codes following a slash.

The <CR> control character maps to \0d. The entire output is completed by a period to enable evaluating the total length of the command string. Otherwise, leading or appended blank spaces will not be visible. A typical Audit message looks as follows:

"{UV} Send: WAVELENGTH=254\0d\0a."

 Tip:

In the Demo mode, there is no output via the serial port!

If the entire input is correctly interpreted, proceed with the following paragraphs. You will find detailed information about format styles and the use of truth tables and lists.
