THE PC LINK (CONTINUED) AND MEASUREMENT PRINCIPLES
The PC may not transmit characters to the counter while this is busy executing the command string. Any character, in particular US, has the same effect as pressing the BREAK key on the instrument: it halts the execution of the command string, and takes the counter back to its start state (default). This may, of course, be used to break off a measurement on purpose.
