only be closed manually.
Any Character/None: The connection will be opened as soon as a character is received
from the attached device. The connection will only be closed manually.

received from the attached device. The connection will be closed if no data is received for
the time specified in Inactivity time.
DSR On/DSR Off: The TCP connection is opened when the DSR signal is on, and closed
when the DSR signal is off.
DSR On/None: The TCP connection is opened when the DSR signal is on. The connection
will only be closed manually.

Packet length
Default 0
Options 0 to 1024
Description This field specifies the maximum amount of data that is allowed to accumulate in the serial
port buffer before sending.
0: Packet length is disregarded and data in the buffer will be sent as specified by the
delimiter settings or when the buffer is full.
1 to 1024: Data in the buffer will be sent as soon it reaches the specified length.
Delimiter 1 and 2
Default Disabled
Options Disabled, Enabled, 00 to FF
Description These fields are used to define special delimiter character(s) for data packing. Enable
Delimiter 1 to control data packing with a single character; enable both Delimiter 1 and 2
to control data packing with two characters received in sequence.
When these fields are enabled, serial data will accumulate in the serial port’s buffer until
the buffer is full or until the specified delimiter character(s) are received. For example, the
carriage-return character could be used as a delimiter in order to transmit each sentence
or paragraph in a separate packet. Data will be packed according to Delimiter process.
Delimiters must be incorporated into the data stream at the software or device level.
ATTENTION
When Delimiter 1 is enabled, Packet length must be set to 0.
