Choose between No Flow Control, RTS/CTS (Hardware Flow Control), DTR/DSR, Xon/Xoff (Software Flow
Control). If Xon/Xoff is selected, Xon and Xoff characters are changeable. Defaults are 0x11 for Xon and 0x13 for
Xoff. If the serial device uses Xon/Xoff in conjunction with DTR/DSR, enable Controlling DTR to simulate
receiving Xon/Xoff and reading DSR to get Xon/Xoff currently.
Empty Serial Buffer When TCP Connection is Established:
By default, SE5001 will empty its serial buffer when a new TCP connection is established. This means that the TCP
application will not receive buffered serial data during a TCP link breakage. To keep the serial data when there is no
TCP connection and send out the buffered serial data immediately after a TCP connection is established, set this
option to No.
Data Packet Delimiter:
Packet delimiter is a way of packing data in the serial communication. It is designed to keep packets in track.
SE5001 provides two types of delimiter: Time Delimiter and Character Delimiter.
 Time Delimiter: SE5001 will transmit the serial data in its buffer when the specified time interval has
reached and no more serial data comes in. The default time is 2ms, which means SE5001 will push out its
serial buffer if it does not receive any serial data with in 2ms.
 Character Delimiter: SE5001 will transmit the serial data in its buffer when it sees the specified character.
The default character delimiter is 0x0d, which means SE5001 will push out its serial buffer if it sees 0x0d
(carriage return) in the serial data.
COM Type Selection:
Select between RS-232, RS-422, and RS-485. Note that RS-485 refers to 2-Wire RS-485 and RS-422 is
compatible with 4-Wire RS-485.
