|Enabled||yes | no; Default: no||Enables the RS232 service|
|Baud rate||300 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200; Default: 115200||Data rate for serial data transmission (in bits per second)|
|Data bits||5 | 6 | 7 | 8; Default: 8||Number of data bits for each character|
|Parity||None | Odd | Even; Default: None||In serial transmission, parity is a method of detecting errors. An extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check.
|Stop bits||1 | 2; Default: 1||Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. Two stop bits are required if slow electromechanical devices are used|
|Flow control||None | RTS/CTS | Xon/Xoff; Default: None||In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a "handshaking" method, usually distinguished between hardware and software handshaking.
|Serial type||Console | Over IP | Modem | Modbus gateway | NTRIP client; Default: Console||Serial connection type. More information on each serial type can be seen below or by clicking on a link in the value section|
|Echo||yes | no; Default: no||Toggles RS232 echo ON or OFF. RS232 echo is a loopback test usually used to check whether the RS232 cable is working properly|
