Option End of Transmission Character (OE)
The end of transmission character is a non-visible character (hexadecimal 0x04) that is
sent at the end of each response by the unit to an RS232 command. The character is
sent after the last carriage-return line-feed returned by the unit with one exception:
when the user is viewing channel values with the @123V(item)(unit)(repeat) and sets
the value of repeat to 2 (streaming output), the character is sent immediately prior to
the streaming output that the unit will send. The OE command enables or disables
this character and its format is: OE(0 or 1), where 0 is disable and 1 is enable.
