You are right.

I had not understood that you continue to use the modem associated  

with /dev/ttySL0

Please send me a copy of the file /etc/wvdial.conf   which you use  

to connect  using ttySL0

i have the 2 configuration in the same file wvdial.conf this is the  

configuration of the external modem tp-link

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = 060110
ISDN = 0
Username = islanis@xxxxxxxxxxxxxx
Init1 = ATZ
Password = **************
Modem = /dev/ttyS0
Baud = 115200

the other configuration i dont have it here because ia am in the work  

right now

The command    mv  /etc/wvdial.conf    myfile.txt    makes a copy  

without changing the original file.

Please hide the password   as you had done before.

I will send you a file modified to use the TP-LINK modem and  

instructions how to use it .

I also need to know what you do to start the other modem before  

giving the command wvdial to use it, because there are several ways  

to do it.

Do you give a command    slmodemd   to start the driver just before  

you need to connect, or is the driver started automatically when you  

boot?

let see, to start the external modem , the tp-link i use

wvdial

to start the smartlink internal modem i use

wvdial interno

later i'll send yopu the entire file ok,,

and i conect only of that way, i dont use the way that are you saying

Juan,

1-In the listing which you have sent,  islanis.txt, there is  

outout of the first four commands only.

The output for

wvdial |  tee  -a  islanis.txt

here is the missing part

root@ubuntu:/home/juan# wvdial
--> WvDial: Internet dialer version 1.60
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
--> Modem initialized.
-> Sending: ATDT060110
--> Waiting for carrier.
ATDT060110
--> Timed out while dialing.  Trying again.
--> Sending: ATDT060110
--> Waiting for carrier.
ATDT060110

is missing.

So I cannot know what happens when you try to connect with wvdial  !!!

Also your /etc/wvdial.conf   contains a section for   /dev/ttySL0

And finally   /dev/modem  too points to   /dev/ttySL0

This ambiguity between    ttySL0 and ttyS0 may fool the system.

If wvdial tries to start ttySL0  but it is your TP-LINK that is  

connected to the wall, it cannot connect to the phone company, and  

this is exactly the problem which you reported.

Please try

1-to remove /dev/modem       with command     rm/dev/modem

2-to remove the script which starts /dev/ttySL0  if it is still  

there.    A way to know for sure is the command      lsmod     

which should NOT show the driver for the other modem (the one you  

used before trying to use TP-LINK)

3-to remove   /etc/wvdial.conf     with command    rm  /etc/wvdial.conf
4-to run wvdialconf again
5-to edit it for the username, phone number, and password as you have done
6-to start    wvdial

ok so, you say that i have to delete /dev/modem and /dev/ttysl0,  

but if i delete them, how i'll comunicate with you, because the  

smartlink modem is the way that i am using to comunicate with you,  

if this, later of this action can not work properly how can i  

restart de configuration to send you the other parts,am afraid of  

that,remember that i am new in this world,and other peoples said to  

me that i can have working some mothems in the same operating  

system, help please

with a very simple basic /etc/wvdial.conf   conaining only ONE  

modem ,    /dev/ttyS0

What you sent definitely shows that the software is recognizing  

the TP-LINK modem as expected. Thus, if wvdial  fails, it can only  

be because the file   /etc/wvdial.conf is bad.

This is why I suggested that you rebuild it from the beginning  

without adding sophistications.

Juan,

Can you please, AFTER HAVING VERIFIED THAT THE TP-LINK MODEM IS
CONNECTED TO PC AND WALL AND POWERED UP, give the  five following
commands as superuser (that is becoming su with most Linux
distributions, or prefixing each command with sudo if you use Debian or
Ubuntu or a variation of Ubuntu or any other variation of Debian) ?
They will create one file named    islanis.txt
