● The value of “
30
" indicates the timeout for the upload
operation.
● The “
ufs:
" string
must
be prepended to the file name in
order for the certificates to function properly.
● It is recommended to name the files “
cacert.pem
",
“
clientcert.pem
" and “
clientkey.pem
" so that they are quickly and
easily distinguishable for later use.
3.
The serial terminal will respond with “
CONNECT
", and will wait for data to be
entered. This data will be entered using the Linux terminal in step 4.
4. Without closing the serial console, issue the following command in a new Linux
terminal, where the name of the file is replaced with the name of the certificate in
question, and the destination is replaced with the appropriate path to the serial
line:
cat VeriSign-Class\3-Public-Primary-Certification-Authority-G5.pem > /dev/ttyUSB0
This command will pipe the contents of the certificate to the serial line, which will
then be stored in a file on the modem.
The serial line will respond with something similar to:
+QFUPL: 1758,384a
Where “
1758
"
is the number of bytes written, and "
384a
" is the checksum for the
operation.
Repeat the four steps listed on the previous page until each of the three files have been
uploaded. Once the files are confirmed to have been uploaded successfully, proceed to
3.1.2
Certificate Uploading Using a Windows Environment
First open the Windows command prompt and navigate to the directory that contains the
certificates that were downloaded in
. Type “
dir
" to list the contents of the
directory on individual lines. Take note of the file sizes of each of the relevant certificates.
This information will be needed shortly.
Next, establish a connection to the modem using a preferred serial console. Once the
serial console has been setup properly, issue the following command to read the contents
of the modem’s file system.

The terminal should respond with something similar to:
OK
