Please, does anyone know if 1841 and 2801 support dial-backup in AUX port using PPP ?
I am trying not use WIC-1AM.
Thanks,

I think you need a chat script to activate the line. Try and add the following to your config (additions are marked by -->):

Hi,
i tried this config on my router, i have to use
'script dialer async' to activate it. it will go on
using default script if 'script connection async'.
now seems the problem is on that script, here is my debug:
ug 3 04:02:17.795: CHAT1: Attempting async line dialer script
*Aug 3 04:02:17.795: CHAT1: Dialing using Modem script: async & System script:

I'm using one TPLink TM-EC5658V Modem.
thanx a lot!

HI
You need to configure the routers at both the sides.What is the response on other side?
Regards
JD
08-02-2006 10:04 PM
i only take responsible for one side,
and the other side is ok, i think, they already got connection with other dialers.
08-02-2006 10:34 PM
Hi
In that case, we will require the config. of other side, b'coz we have to make sure that you are using their settings.The debug output seems to be OK with your side, there is some issue with the remote side.

hi,
i got a news really really bad. maybe the problem is on my line, connecting modem and aux!
u know to connect modem i need a RS232-Rj45, and the RS232 head should be male.
there is one line shipped with router, RS232(female)-RJ45, so i bought one male-male commutator for it.
now i guess this commutator is the criminal.
i checked the AT commands by connect the modem to COM2 directly, and they can work.
and i noticed when the modem connect to computer, status light of 'TR' which means DTE ready is on.
but when i connect modem to router, TR is off!
what's very strange is, with this commutator, the router can find the async interface, after i config
aux.
how can i make sure the commutator is ok?
if not, how can i make one line, i mean how is the order of that line?
many thanx
