Input buffer
•
Commands can be sent all at once up to the input buffer’s capacity (approximately 4,000

interpreted (parsed) and executed.

If an illegal command is found during interpretation or execution, subsequent commands are
not executed.
•
When interpretation and execution are completed, the input buffer is cleared, so that the next
command can be input.
