ZTE MG880 CDMA USB Modem on Puppy Linux

Reliance India provides ZTE MG880 CDMA USB Modem and one friend of my son-in-law arrived yesterday with a Laptop on which Windows partition was reformatted recently and he had no driver CD for the Modem. In addition sound was not working on the Windows desktop.

I popped in Puppy Linux 4.0 CD into his Laptop and showed him how to mount his Windows NTFS partitions and started playing one MP3 file from D:/ drive. Then I opened one .doc file into Abiword. He was very much impressed. Then he gave me the USB modem and asked me how to connect.

Puppy Linux could detect the modem but could not load the module. I googled and found the solution which was working on Ubuntu.
# modprobe usbserial vendor=0x19d2 product=0xfffd

and to use the following /etc/wvdial.conf file:
[Dialer zte]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = #777
Username = 93XXXXXXXX
Password = 93XXXXXXXX
ISDN = 0
SetVolume = 0
FlowControl = Hardware (CRTSCTS)
Modem = /dev/ttyUSB0
Dial Command = ATDT
Baud = 460800
Stupid Mode = 1

The above configuration did not work on Puppy. Then I found that Puppy was linking the modem to /dev/USB/ttyUSB0, accordingly, I changed the Modem= line to:

After changing the line I got following error:
PPP daemon dies (exit code =2).

On checking /var/log/messages following errors were found:
(none) daemon.err pppd[6304]: Can't open options file /etc/ppp/peers/wvdial: No such file or directory
(none) daemon.err pppd[6317]: Can't open options file /etc/ppp/peers/wvdial: No such file or directory
(none) daemon.err pppd[6352]: Can't open options file /etc/ppp/peers/wvdial: No such file or directory

I copied the file /etc/ppp/wvdial into /etc/ppp/peers directory and finally, I could connect to internet.

He wished that there was Skype on Puppy. I got the link for .pet for Skype on Puppy Linux Forums and installed.

I think I have added one user in the Puppy Linux community.
