asynchronous communication, but it also uses a common time base or
|
||
clock, as does synchronous communication.

||
a control character used to terminate an intermediate block of
|
||
characters. The block-check character is sent immediately following
|
||
ITB, and line-turnaround does not occur. The response following End of
|
||
Transmission Block (ETB) or End of Text (ETX) also applies to all of
|
||
the ITB checks immediately preceding the clock terminated by ETB
|
||
or ETX.
