6.1.6 End of Message (EOM)
RS232 Communications Mode: when the ControlMaster is set to communicate via
RS232 communications, the EOM string is required. The EOM is different when
the ControlMaster receives data or transmits data to a host device.
Data Reception by the ControlMaster from the Host computer: the End of
Message is defined as an ASCII Carriage Return, i.e., 0x0D Hex, CR, character
(only for RS232, otherwise it is Empty), and is symbolized by the EOM symbol.
This is used by the ControlMaster to identify the completion of the reception of
the data or command.
Data Transmission by the ControlMaster to the Host computer: the End of
Message is defined as an ASCII Carriage Line Feed, i.e., 0x0D0A Hex,
CR + LF, characters (only for RS232, otherwise it is Empty), and is symbolized
by the EOM symbol. The ControlMaster transmits a message to the Host; it
terminates the message with the End of Message (EOM).
NOTE
The EOM is required only for RS232!
