My modem is recognized. It is a different card than before.

  $dmesg | grep -i tty
console [tty0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:05: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

then :
  $wvdialconf  /etc/wvdial.conf
Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

ttyS0<Info>: Device or resource busy
Modem Port Scan<*1>: S0
ttyS1<Info>: Device or resource busy
Modem Port Scan<*1>: S1
ttyS2<Info>: Device or resource busy
Modem Port Scan<*1>: S2
ttyS3<Info>: Device or resource busy
Modem Port Scan<*1>: S3

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

This is where i got stuck before. I am not using setserial properly. I 
can execute the command but i am assigning the wrong values i think but 
my syntax is ok or I would get an error from bash. One thing,at least, 
is clear, i do not understand the setserial command or what to set the 
values to.
