Upon completion of the ICP theecho process would wait for data from the network.  When the data isreceived from the network it is echoed at once, (and the buffer space isre-allocated).  By echoed I mean that the data received is sent backover the network, bit for bit with no modification by the echo process.The echo process is terminated by closing the network connections.Note that BBN-TENEX has had such an echo process available for use for along time.
