+===== PPPD
+This is the recommended method for establishing a connection when using the SARA R410 and Ubuntu. 
+
+To configure a connection to the Hologram network execute the following commands:
+
+* Install pppd
+{{{#!bash
+apt-get install ppp
+}}}
+* Disable ModemManager
+{{{#!bash
+systemctl stop ModemManager
+systemctl disable ModemManager
+}}}
+* Create the following files
+{{{#!bash
+cat <<EOF >> /etc/chatscripts/sara
+# Chat script for Hologram Nova using Hologram SIM card
+# See hologram.io for more information
+
+ABORT 'BUSY'
+ABORT 'NO CARRIER'

+cat <<EOF >> /etc/ppp/peers/sara
+# PPP configuration for Hologram Nova modem using Hologram SIM card

+# Use this connection as the default route.

+

+persist

+# Do not ask the remote to authenticate.

+# interfaces(5) file used by ifup(8) and ifdown(8)

+source-directory /etc/network/interfaces.d
+#allow-hotplug eth0
+#auto eth0
+iface eth0 inet dhcp
+
+auto ppp0
+iface ppp0 inet ppp
+provider sara
+EOF
+}}}
+{{{#!bash
+cat <<EOF >> /etc/network/if-pre-up.d/sara
+#!/bin/sh
+
+if [ "$IFACE" = ppp0 ]; then
+        DEVICE=/dev/$(for i in $(ls -d /sys/bus/usb/drivers/option/*/ttyUSB*); do basename $i; done | tail -n1)
+        sed -i 's;/dev/ttyUSB[[:digit:]]*;'"$DEVICE"';' /etc/ppp/peers/sara
+        echo "ppp0 up"
+        echo "AT+COPS=2" > $DEVICE
+        echo "AT+UMNOPROF=0" > $DEVICE
+        echo "AT+UMNOPROF=3" > $DEVICE
+        echo "AT+CFUN=15" > $DEVICE
+        sleep 10
+fi
+EOF
+}}}
+
+Execute the command "sync", then reboot.  If there are no typos or discrepancies the interface "ppp0" should be available with a dhcp assigned address.  
+
+To troubleshoot check that the command below returns the correct device:
+
+{{{#!bash
+echo /dev/$(for i in $(ls -d /sys/bus/usb/drivers/option/*/ttyUSB*); do basename $i; done | tail -n1)
+}}}
+
+Note: name resolution will need to be configured.
