usb-serial and PPP

[Mohan V]

Hello all,

I am using Triton board with linux-2.4.19-rmk7-pxa1. I am using 
usb-serial driver to get the ppp interface on the board. On the host 
(Mandrake 10, 2.6.3 kernel), I am using the MPPP client for dialing.

I give the command on the host and I get the following:

mppp -quit 0

LCP: timeout sending Config-Requests

On the device side, I am using an application, which on receiving ATDT 
command starts the pppd with the following options:
pppd /dev/usbser 192.168.100.1: 192.168.100.2 9600 noccp nomp -detach 
nocrtscts nocdtrcts noauth proxyarp passive debug
I am getting the following messages:

If i do ifconfig I get the ppp0 interface but with no inet and P-to-P 
address.

Do you get the same thing with a more current PXA kernel
using the more current USB drivers?  Maybe 2.6.9 or so.

As a rule, for a kernel that old you're going to have to
rely on your vendor to support you.  You'd even have a
hard time getting support for that on the ARM list...
as was pointed out to you the LAST TIME you asked a
question about 2.4.19-rmk7-pxa1 kernel and that driver.
