Looks to me like an authentication problem. In the chat script there doesn't appear to be any authentication occurring. Check your chat script and if you would like me to look at the chat script comment it here for me,

Regards,

Jason

Hi unicorntech,

   It looks also to me as authentication problem.
 I am reading this message from my office.
 I will give my chat script over two hours.

 Thanks, klivlend.

My chat script:

# It will perform the connection
# protocol for the desired connection.

How To Install Bash on Windows 10

Windows’ budding partnership with Canonical has certainly led to some great improvements. One of them being the ability to use Bash on your Windows machine without third party applications! This might be one of the greatest things a cloud engineer in a Windows environment can do!

The chat script is not sending the following sequence:
name: my_username \
assword: my_passwd
Are you sure that the login prompt is name or username and not Login or login?

Hi Jason,
  First, it's a sequence, that I get in minicom:
          Username:
          Password:
  Second, login: sequence doesn't establish connection at all.
Bye, klivlend.

I think the problem is in this line :
CONNECT '' \
try using CONNECT \
instead.

Let me know how you go...

Jason

PS - If you go throught the script log you see that CONNECT is received from the remote end - then you send a carriage return then nothing. Another way to do this would be to create a script called dial and in it put the following:

pppd defaultroute /dev/cua1 connect 'chat "" ATDT(provider no) name: username word: password'

Make it executable and try that by typing dial

However if you want to use ppp-on let me look into it further for you.....

 Hi unicorntech,

     I solved my ppp-chat connection problem.
     It became clear that it isn't allowed
     to include commeneted lines like
       # uthentication \
       # ogin:   xxx   \
       # word:   yyyyy \
     This is bug for my chat. I wonder that this
     problem isn't known. May by it's depend on
     chat version?

     Thanks,klivlend.
