Serial Ports

The serial ports support RS-232, RS-422, and RS-485 2-wire operation modes with flexible baudrate settings.

The default operation mode is set to RS-422. Use the

setinterface command to change the operation

mode as follows:

Usage: setinterface device-node [interface-no]

Device-node: /dev/ttySn; n = 0,1,2,...

Interface-no: Refer to the following table

Interface

Number

Operation Mode

None Display current setting

0 RS-232

1 RS-485 2-wire

2 RS-422

3 RS-485 4-wire

For example, to set /dev/ttyS0 to RS-485 2-wire (RS485-2W) mode, use the following command:

moxa@Moxa:~# sudo setinterface /dev/ttyS0 1

Now setting is RS485-2W mode

moxa@Moxa:~# sudo setinterface /dev/ttyS0

UART Port#0 is in RS485-2W Mode

stty

The stty command is used to manipulate the serial terminal settings. You can view and modify the serial

terminal settings with this command as described below:
