Serial ports
By default, the LED state of RS-232, RS-422, and RS-485 is OFF. It is only ON when data is being transmitted. The device
nodes are ordered by the port position starting with the left-most port (RS-232).

RS-232
Ready-to-use software to control or manage devices are not available from Dell.
To configure the RS-232 port, run the following commands:
1. Set RS232 from the pre-installed DCC application.
$ dcc.cctk -h --serial1
$ dcc.cctk --serial1
$ dcc.cctk --serial1=rs232
2. Set serial port mode.
$ sudo stty -F /dev/ttyXRUSB0 ispeed 115200 ospeed 115200 -echo -onlcr -ixon -ixoff
$ sudo stty -F /dev/ttyXRUSB1 ispeed 115200 ospeed 115200 -echo -onlcr -ixon -ixoff
3. Transfer or receive data between two ports—for example, a wired RS-232 between two serial ports on the device.
$ sudo su
$ echo abcdefg > /dev/ttyXRUSB0
Repeat the command to send data.
4. Receive data from another terminal by ssh from your computer.
$ ssh admin@<IP address of Edge Gateway>
(passwd: admin)
$ sudo su
$ cat /dev/ttyXRUSB1
Verify that the string is received correctly.
