dial-up connection

hi guy`s ..

i face a big problem with my modem .

my modem is : US.Robotics fax modem 56kb and i connect it with Serial Port and i try dial-up connection but it`s failed .

i open the kppp and enter the information for my account and i press connect

and when i wait for a moment this message appear
the pppd daemon died unexpectedly
Exit status : 16

and this is the Login Script Debug

ATZJ
OK
ATM1L3J
OK
ATDT3606060

CONNECT 45333/ARQ/V92/LAPM/V42BIS

i am using FC3

and very sorry for my very bad English

hope someone help

US.Robotics fax modem 56kb modem is not fully supported. More info at http://veera.bizhat.com/sm56
Or try searching google for US Robotics modem linux

http://www.linmodems.org/

1) Run the "scanmodem" tool from the website to find the exact chipset.

2) It will tell you exact chipset your modem has and then will make suggestions about the drivers.

Good Luck

I have the same problem with a USR external modem. It was recommended as a good "Linux" modem (I have tried it with Mandrake 10.1, Fedora Core 2&3, Debian 3.0, and Knoppix) and it wasn't. I bought a Best Data 56K and it has seemed to cure my problem. I have Googled and forumed to death on the answer for my USR to no avail. I am still looking for the answer as I have the USR on one of my Debian boxes and still try if from time to time in hopes of finding the cure. If all else fails and I am lucky they will get DSL into my rural area soon. Good Luck.

ammm , so the problem is in the modem !
that`s what i think ..

but the big problem is that all poeple say`s that
usr external modem with serial port is the best to use it in ur linux box .. and that`s un-true

i really try to do all the solution to fix this problem but nothing happenS

i try both kppp and wvdial but without results !!

and this is how i create a connection :

first /

Code:

[root@localhost ~]# wvdialconf /etc/wvdial.conf

Found a modem on /dev/ttyS3, using link /dev/modem in config.

Modem configuration written to /etc/wvdial.conf.

ttyS3<Info>: Speed 115200; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

----- second i enter my account information as shown here

i enter here
vi /etc/wvdial.conf

then i edit the information

Code:

[Modem0]

Modem = /dev/ttyS3

Baud = 115200

SetVolume = 0

Dial Command = ATDT

Init1 = ATZ

Init3 = ATM0

FlowControl = CRTSCTS



[Dialer Defaults]

Modem = /dev/modem

Baud = 115200

Init1 = ATZ

Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

ISDN = 0

Modem Type = Analog Modem

Phone = *******

Username = ******

Password = *****

after that i try to connect with typing wvdial

and this is the logs

why the connection is disconnecting ??

Hello vstealerv,

Try in KPPP to change the INIT string, you can Google for you INIT strings or maybe your modem is on this page http://modems.rosenet.net/inits.php/116

US Robotics not always works with standard INIT string's.

You can forget some of the postings here, there are no Serial RS-232 Windows soft-modems, also you not have to know which chipset your US Robotics uses...it is US Robotics.

of i`ll buy a new modem what do u suggest ?

alcatel - speed touch
motorolla
or wut ??

uppppppppppppppppppppppppp

I am using a US Robotics/3Com 56k FaxModem Model 5610 and it works with Mandrake 10.1 and Vector linux. But I also have a US Robotics 56K Fax Modem that is a winmodem and it won't work with linux. So if your modem doesn't have the controller on it, like the man said, you will need to get another one.
