Error Queue
If an error occurs due to invalid input or buffer overflow, its error code is sent to the error
queue. The error code can be read from the queue with the command FAULT?. The error
queue holds 15 error codes. When it is empty, FAULT? returns 0. The error queue is cleared
when power is reset or when the clear command *CLS is entered.
Input Buffer

characters are processed on a first in, first out basis.
