Hi Ram >> edited RC Local with the lines' >> sudo -S modprobe usbserial vendor=0x0451 product=0x3401 >> </home/ram/foo/foo.txt >> sudo mknod /dev/ttyUSB0 c 188 0 >> sudo mknod /dev/ttyUSB1 c 188 1 When I was trying the configuration for the first time I did all this from the command line, not from rc.local or anywhere else. So, lets try this:
1. Change your rc.local to the original state. 2. Change your /etc/modprobe.d/ to the original state too. 3. run the above commands without the password file, just enter the password manually, all three in the above sequence. 4. backup your /etc/wvdial.conf and create a clean /etc/wvdial.conf, with the following lines: [Dialer Defaults] Modem = /dev/ttyUSB0 Init1 = ATZ Phone = #777 Username = cdma Password = cdma New PPPD = yes Stupid Mode = 1 This is the exact wvdial.conf I am using. As you can notice, there are no pppd options. And try connecting using sudo wvdial. Sometimes, it will take almost 90 seconds to connect, so go make tea or have a cup or coffee or something, in case it is taking unusually long to connect. It just might after a long time. 5. If this does not work, try installing minicom or something similar and try sending commands to the ETS2288 directly using mincom and see if it responds correctly. I got my ETS1201 working as above first, used that, and found no one could deal with running wvdial from the shellprompt, so I have installed GNOME-PPP and it works well with that for the past month or so. And GNOME-PPP is using the following file (this is the exact copy): [Dialer Defaults] Modem = /dev/ttyUSB0 ISDN = off Modem Type = Analog Modem Baud = 115200 Init = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = Init4 = Init5 = Init6 = Init7 = Init8 = Init9 = Phone = #777 Phone1 = Phone2 = Phone3 = Phone4 = Dial Prefix = Dial Attempts = 3 Dial Command = ATM1L3DT Ask Password = off Password = cdma Username = cdma Auto Reconnect = off Abort on Busy = on Carrier Check = on Check Def Route = on Abort on No Dialtone = on Stupid Mode = on Idle Seconds = 0 Auto DNS = on ;Minimize = off ;Dock = on ;Do NOT edit this file by hand! Tell me if this works for you. If all this works, only then create the appropriate /etc/rc.local and /etc/wvdial.conf. I am beginning to read about the ETS2288 in case I can find something about it.
