(3) Error Detection
If the recorder receives the data that has resulted in a signal error such as parity error, framing error,
etc. due to the noise or hardware troubles, it will ignore that data. Consequently, a data format error
results, determining that the data is not sent in the normal data format. The received function does not
execute that command and the transmitted function does not reply. The data format error status can be
confirmed by the ESC S command (described later).

8.2 Opening/Closing the Link
To communicate with the recorder, you must establish a connection between the host computer and
the recorder. In the case of one-to-N communications, it is necessary to inform each recorder to which
recorder the text is being sent. If a link open command is sent to multiple recorders through their send
function, all the recorders, which have received the command, will send and cannot receive the normal
data.

If it is required that the data is sent to the recorders other than the open command is issued, this
close command must be issued to those recorders open command was issued.
