"Block mode" in terminalsthe characters you type are temporarily retained in the terminal memory (and may possibly be edited by a built-in editor at the terminal). Then when the send key is pressed, a block of characters (sometimes just a line of characters) is send to the computer all at once. Block mode is not supported in Linux.
