PPP DialUp connection in NodeGrid Serial Console

NodeGrid Serial Console supports DialUp via USB modems. It does not support via serial ports.


You can plug any USB modem such as Zoom or USRobotics  to any of the NodeGrid Serial Console USB ports.

Then, follow the steps below:

a.       Log in as admin to the NodeGrid WebUI

b.       Go to System, Dial Up page

c.       Under Services tab, enable PPP connection

d.       Under Devices tab, click on Add button

e.       Complete the parameters accordingly. The “Detected Devices” should show something like ‘usbM1-4’

f.       After the parameters are complete, click on Save. (NOTE: leave “PPP Dial-Out Phone Number” blank if you want it to be Dial-IN; if you want it to be Dial-OUT, then add the phone number)

g.       Add callback users and phone numbers under CallBack Users tab, if that is the case.

Configuration via CLI

a. log in as admin to the NodeGrid CLI

b. type the following:

      cd /settings/dial_up/services

      set ppp_connection=enabled



      cd /settings/dial_up/devices/


      show  (it will list the current settings)             

name =  

status = disabled

device_name = usbM1-4

detected devices: usbM1-4

speed = 38400

phone_number = 

ppp_idle_timeout = 0

init_chat = 

ppp_ipv4_address = no_ipv4_address

ppp_ipv6_address = no_ipv6_address

Make the necessary changes for the parameters accordingly:

      set device_name=<name>

      set status=enabled

      set speed=

            115200  19200   38400   57600   9600  

      set ppp_ipv4_address=

            local_ipv4       no_ipv4_address  remote_ipv4
