3G USB modems can have multiple /dev/ttyUSB[n] ports.

Here is a test that works for my Optus Huawei E160E modem:

...see blog post, there is a request, does this work for your 3G modem?

Barry,

Pristine boot of Q130: hotpluged Huawei E1550 has 3 /dev/ttyUSB items
/dev/ttyUSB0 and /dev/ttyUSB2 return imediately with the blank line and OK but /dev/ttyUSB1 does not return for at least 4 minutes. I connect with /dev/ttyUSB0.

Now where is that P431 CD...

while connected on asus eeepc 1005 with integrated huawei modem the modem-stats -c "ATZ" /dev/ttyUSB* shows the following :
# modem-stats -c "ATZ" /dev/ttyUSB0 > no output

# modem-stats -c "ATZ" /dev/ttyUSB1 > blinking cursor (hangs, escaping by Cntr C)

# modem-stats -c "ATZ" /dev/ttyUSB2


OK

# modem-stats -c "ATZ" /dev/ttyUSB3
modem-stats: Can't open /dev/ttyUSB3 for reading and writing.
Usage: modem-stats [-c command] [-e end_string] device

The acer extensa5230E with huawei K3715 USB-Pen while not connected shows following :
# modem-stats -c "ATZ" /dev/ttyUSB0


OK
# modem-stats -c "ATZ" /dev/ttyUSB1 > blinking cursor (hangs, escaping by Cntr C)

# modem-stats -c "ATZ" /dev/ttyUSB0

OK
and some minutes later
23 lines with ^BOOT
3 lines with ^RSSI
OK

# modem-stats -c "ATZ" /dev/ttyUSB3
modem-stats: Can't open /dev/ttyUSB3 for reading and writing.
Usage: modem-stats [-c command] [-e end_string] device


Both Net and LapTopBook are connecting fine on ttyUSB0 by pgprs-shell -connect with two telephone companies.
There seems to be no difference between ATZ and ATV1Z here but it seems that the output at ttyUSB2 differs each time :
sometimes many lines with ^BOOT \n OK
sometimes one line with ^BOOT \n OK
the next try no ^BOOT \n OK
and another try one A \n(\n) OK

I remasterd these two dpup-005 and they don't show the fourth ttyUSB3 ....

PostPosted: Sat 04 Dec 2010, 02:29    Post subject: 3G test result  

Acer 5220 Laptop.
Huwae E1762 modem
Optus Carrier
Lupu-510 (Lucid Puppy)
Modem recognised on desktop as SR1 whether hot plugged or inserted at boot up.
No internet connection established prior to testing.

Typed in terminal:
modem-stats -c "ATZ" /dev/ttyUSB0 and then substituted USB1, 2 and 3 for 0.

Results over several tests:
USB0
Blank line
OK

USB1
Blank line
OK

USB2 and USB3
modem-stats: can't open /dev/ttyUSB2 (3) for reading and writing.
Usage: modem-stats [-c command] [-e end_string] device

Also just noticed that the Lock and Zip icons on the desktop are superimposed over one another, but that would be a separate issue.

HTH,
Cheers!

Do you have a 3G modem that uses the 'hso.ko' driver?

If so, you can help out, I have posted another request:

Barry,
Please note that the usb_modeswitch package includes a udev rule that creates symlinks to the ttyUSB ports that are likely to work. If multiple candidates are detected, your only task is to distinguish which is the full data port. My implementation merely picks one (now, the highest), but your new logic can make that decision. The symlinks are created regardless of the need for a mode switch, it appears to me. The rule:
Code:
# This adds a symlink "gsmmodem[n]" to ttyUSB ports with interrupt transfer;
# will work only with wrapper from 1.1.4 and above (otherwise ignored)
KERNEL=="ttyUSB*", DRIVERS=="option1|usbserial", PROGRAM="/usr/bin/tclsh /usr/sbin/usb_modeswitch_dispatcher --symlink-name %p", SYMLINK="%c"
"dispatcher --symlink-name" provides the ttyUSB port for the link.

Richard,
I don't know why, but this does not work for my Optus Huawei E160E modem. This is the only modem I have right now.

When I get my hands on more 3G modems, I will see if they create the links.

Samsung X05
Huawei E169G
luci_241

First boot of luci_241 with E169 inserted.
/dev showed all three ttyUSB0,1 and 2 present.
/var/log/messages also reports that the option module had been installed.
Opened up the terminal and typed "modem-stats-c "ATV1Z" /dev/ttyUSB0" , response " command not found".
Does this command need the dev.sfs package installed to function?

Fired up PupDial and was pleasantly surprised to see that it was already set up on the ttyUSB0 port rather than the onboard dial-up modem.

Posting this now from luci_241 using the E169 modem.

There has been a lot of water under the bridge since this thread was started.

Wary Puppy 5.0 has my latest 3G modem code. Download Wary and give it a spin:

And monitor my blog for further progress.
