wvdial: The PPP daemon has died: Pty program error (exit code = 9)

Question

I tried to configure AnyDATA ADU890-WH modem to work in Linux, but I have not succeeded. I am client of Czech carrier O2 and using Ubuntu 14.04.

I have once managed to connect using Network Center, Mobile Broadband tab - but since then I have not succeeded.

This is my wvdial.conf:

[Dialer Defaults]
Init2 = ATQ0 V1 E1 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = *99#
Stupid Mode = 1
ISDN = 0
Username = a
Init1 = ATZ
Password = a
Modem = /dev/ttyUSB0
Dial Command = ATDT
Baud = 9600

[Dialer CDMA]
Auto DNS = 0
Init1 = ATQ
Init2 = ATZ
Stupid Mode = 1
Phone = #777
Idle Seconds = 0
Modem = /dev/ttyUSB0
Username = [email protected]
Dial Command = ATDT
Password = xxxxxx
Baud = 1500000


[Dialer three]
Init2 = ATZ
Init3 = ATQ0 V1 &D2 &C1 S0=0 +IFC=2,2
Init5 = AT+CGDCONT=1,"IP","internet"
ISDN = 0
Modem = /dev/ttyUSB0
Modem Type = Analog Modem

And this is important part of /var/log/syslog file:

Jul 23 20:25:07 wigos-hp-lx pppd[5524]: Exit.

I have also found some guides how to set up the connection without wvdial - but these guides rely on starting the connection by pon <connection-name>, but when using this command, I get no output and nothing happens.

The modem supports also CDMA network, but the error when using wvdial is the same.

By some trial and error, I found following section in my /etc/ppp/options:

# BSD licensed ppp-2.4.2 upstream with MPPE only, kernel module ppp_mppe.o
# {{{
refuse-pap
refuse-chap
refuse-mschap
# Require the peer to authenticate itself using MS-CHAPv2 [Microsoft
# Challenge Handshake Authentication Protocol, Version 2] authentication.
require-mschap-v2
# Require MPPE 128-bit encryption
# (note that MPPE requires the use of MSCHAP-V2 during authentication)
require-mppe-128
# }}}

Commenting out all those refuse-* and require-* options made the authentication (and connection) succeed.
