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?
