dial-up configuration problem

John712_1 — Thu, 27 Oct 2005 20:00:58 GMT

just fit in a Hayes Accura V.90 modem in my c3000. the devices files /dev/cul0p0, /dev/ttyd0p0, /dev/cua0p0 are created by sam.

/usr/lib/uucp/Devices is modified as:
ACU cul0p0 - 57600 hayes
Direct cul0p0 - 57600 direct

two lines are added into /etc/inittab:
vue :4:respawn:/usr/vue/bin/vuerc
#ttp0:234:respawn:/usr/sbin/getty -h ttyd0p0 9600

when run command # cu -s57600 -lcul0p0 dir, it responses: "Connected"

when run command #cu -s57600 xxxxxx(phone number here), it show msg:"Autodialing - please wait". after a few munites, it response:"Connect failed: no answer".

The phone number is correct, and the cable is also pluged in. So what's problem? why cannot connected?

thanks in advance.

Local configuration looks ok as you could able to dial out.

The problem should be with remote modem which is not answering.

Check the remote is configured for auto answer and look for DTR , speed. The remote configuration should for dial-in.

Hi,

As indicated earlier could you confirm the functionality of the modem at other end.

What does the remote modem do when you dial the number from a handphone ?

What if you connect to remote modem through some other dialout modem?

Many thanks.

Sameer, I am completely new to unix, so what do you mean by "remote modem"? Do you refer to the Hayes Accura V.90 which was physicall fitted in the c3000? and how to configur it?

Devender, the phone number is provided by my university, there is no problem for me to connect to internet with this phone number using my laptop. If dial from a handphone, it would be bussy tone. And you also mentioned "another modem", are you talking the same modem as Sameer? do you know how to configur it?

Hi,

The remote modem or other modem here refers to the modem connected to other machine you are dialing to.

by the way, the Hayes modem is physically fitted in the No.5 PCI slot, and when configuring the modem with SAM, there are 2 hardware path for choose:
(1)10/0/14/1/1 asio0 Built-in RS-232 Interface
(2)10/0/14/1/2 asio0 built-in RS-232 Interface

In my configuration, I choose the first, is that correct?

Also I tick the options of "Use Device for Calling Out", and "Receive In-Coming Calls (start getty process)".

I did NOT tick those options: "CCITT Modem (European standard modems)" and "Use Hardware Flow Control Device Files (RTS/CTS protocol)"

Many thanks, Devender. I am dialing from home to the university server. what the university gave to me is the username and the password and the dial-up phone number. That's my current state.

So how can I configure the "remote modem" which is supposed to be in the university?

Hi,

In my earlier post, I mean to dial the line connected to remote modem.

In this event the modem shall give you a hand-shake sound when you dial it from a handphone. Is it doing that ?

Another try would be to test the dialin connection to remote modem by using any other working setup of dialout modem.

When run the command #ioscan -f, it shows an unknown device:

Class I H/W Path Driver S/W State H/W Type Description
================================================================
unkown -1 10/1/5/0 (no driver info) UNCLAIMED UNKNOWN PCI SimpleComm(11c10458)

================================================================

is the unknown device the modem?
