I have a Motorola SM56 PCI Fax Modem (internal). I am using the driver
given in the PCQLinux 7.1 distro (sm56-85.1-10.i386.rpm). I have
checked that the modem is working properly.
I configured kppp as per the instructions given in the PCQ August issue
(Pg 112, 113). The only ambiguous instruction was regarding the type of
authentication used by the ISP. The options offered are PAP, CHAP,
script-based and terminal-based. My ISP is VSNL and I don't have a clue
what it requires so I chose terminal-based.
kppp dialed into the VSNL server successfully but after a few seconds pppd
died because of this error:
"Error 17: The PPP negotiation failed because serial loopback was detected."
What is serial loopback? What can I do to avoid this error?
Thanks.

Sometime Today, Parul Mathur assembled some asciibets to say:
the type of authentication used by the ISP. The
options offered are
PAP, CHAP, script-based and terminal-based. My ISP is VSNL and I
VSNL supports PAP, script and terminal. PAP is where the system does
authentication through exchange of certain info. script is where you
have an expect script read from the line, and write to it in exactly the
same way as you would. terminal based is supposed to bring up a
terminal for you to type your username and password.
This is what didn't happen, which is why pppd died.
You need to configure it as script-based, and enter required details in
your script.
There are easier ways however.

I also have the same modem and same driver installed on SuSE 7.1.
It used to work great untill last week. Since last week or so,
I'm also getting the same message while connecting. My ISP is
Roltanet and I'm using wvdial for connecting to the net. I also
tried connecting using Kppp, but as expected it also detected
serial loopback. I also have the same question, what is serial
loopback? Some times, if i dial in as a root, then I used to get
connected, but since last couple of days, even that has also
stopped.
Btw, for allowing all the users on my home PC system, chmoded
/dev/modem to 777. Is this okay or is there some better
workaround? I did this becoz I read somewhere in our mail
archives that one shud not dial-up as root for the sake of
security reasons.
Thanks a lot in advance.

The serial loopback error occurs when the pppd program tries to execute
before a connection to the remote server is completed. In order to elimiate
this problem be sure to place the following in your chat script.
CONNECT 'CONNECT' \

I don't use chat scripts. I use wvdial or kppp. I'm not aware of
how to use chat scripts. What do I do?
