IEEE-488.2 Common Commands
The IEEE-488.2 standard defines a set of common commands that perform
functions such as reset, self-test, and status operations. Common commands
always begin with an asterisk ( * ), are three characters in length, and may
include one or more parameters. The command keyword is separated from the
first parameter by a blank space. Use a semicolon ( ; ) to separate multiple
commands as shown below:
*RST; *CLS; *ESE 32; *OPC?
