The subterminal does not respond if the address is different from its own address, 
or if an error has been detected, or if the two address characters are different. The 
control unit repeats the receive poll after an internal time-out.

no 

response 

 

If the address has been detected correctly, the receive poll is acknowledged by the 
subterminal by ACK0. After that the control unit sends the data record, which is 
acknowledged by ACK1 if correctly received. If the control unit receives a correct 
acknowledgement, the control unit terminates the transmission by sending an EOT.

If the control unit’s data record has not been received correctly, the subterminal will 
acknowledge by sending an NAK until the record has been understood.

If the control receives no correct acknowledgement, it will send an ENQ to request 
a retry of the acknowledgement.
