5: Serial Port Configuration
To attach the serial device to the LS100 serial port, its serial port operation should match exactly to that of the serial device. Serial port configuration parameters are summarized in Table

| |
Parameter | Values | |
Baud rate | 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 | |
Data bits | 7 bits or 8 bits | |
Parity | None, Even or Odd | |
Stop bits | 1 bit or 2 bits | |
Flow control | None, Hardware (RTS/CTS) | |
DTR option | Always HIGH, Always LOW, or Show TCP connection | |
DSR option | None, Accept TCP connection only by HIGH, or | |
Open/Close TCP connection | ||

To configure serial port parameters, use ‘set’ command as follows:
set serial baudrate data_bits parity stop_bits flow_control dtr_option dsr_option interchar_timeout(ms)
where,
baudrate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200
data_bits:
parity: n=none / e=even / o=odd
stop_bits:
flow_control: n=none / h=hardware
dtr_option: h=always high / l=always low / s=show tcp connection
dsr_option: n=none / a=accept only by high / o=open,close TCP connection
interchar_timeout:
The factory default settings of baud rate, data bits, parity and stop bits are 9600, 8 data bits, No- parity and 1 stop bit respectively. Among the serial configuration, there are three serial modes the LS100 does not support. The LS100 does not support 7 data bits, No parity, 1 stop bit configuration. In this case, the LS100 will operate as 7 data bits, No parity, 2 stop bit mode. In case the LS100 is configured as 8 data bits, Even(or Odd) parity, 2 stop bits mode, the LS100 will operate as 8 data bits, Even (or Odd) parity, 1 stop bit mode.
The factory default setting of the flow control is None. Only hardware flow control using RTS/CTS is
