WAIt for completion suffix
GPIB port control
Causes the generator to wait until all processes have been completed before sending the
prompt. Normally, the generator returns a prompt immediately after either an FMTU,
IMGU, ALLU, BOOT, INIT, or SCAL command is received, even before these commands
have finished executing. If the system controlling the generator must know when a
command has finished executing, use a semicolon to append the suffix ... ;*WAI. .
