help! use pyhumod in RHEL 4.2 with EC325
mistletoe
find the pyhumod with google. It is seemed to be good. But i got
some problems.
First, my linux is RHEL 4.2. Dbus version in it is dbus-0.22-12.EL.
9. When I ran the script: find_huawei_iface. I got the error:
AttributeError: SystemBus instance has no attribute 'get_object'.
I tried my best to solve it but I failed.
Second, because ec325 is a cdma device, I change the pyhumod-0.02/
default.py :
DATA_PORT = '/dev/ttyUSB0'
CONTROL_PORT = '/dev/ttyUSB1'
PPPD_PATH = '/usr/sbin/pppd'
PROBER_TIMEOUT = 0.5
BAUDRATE = '115200'
DIALNUM = '#777'
PPPD_PARAMS = ['modem', 'crtscts', 'defaultroute', 'usehostname', '-
detach',
'noipdefault', 'call', 'humod', 'user', 'card',
'usepeerdns',
'idle', '0', 'logfd', '8']
in the /etc/ppp/pap-secrets file:
card pdsn card
when I entered this code in python:
>>> import humod
>>> m = humod.Modem()
>>> model = m.show_model()
I waited and waited, but nothing happened. In the end I ended the
command with "Ctrl + C", the messaged I got was:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.3/site-packages/humod/at_commands.py", line
239, in show_model

File "/usr/lib/python2.3/site-packages/serial/serialposix.py", line
317, in read
ready,_,_ = select.select([self.fd],[],[], self._timeout)
KeyboardInterrupt
by the way, I show the message that I success to get when I use the
wvdial and pppd.
my /etc/wvdial.conf:
[Modem0]
Modem = /dev/ttyUSB0
Baud = 115200
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = CARD
Password = CARD
Phone = #777
Stupid Mode = 1
Inherits = Modem0
when I enter in:
# wvdial cdma&
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Modem initialized.
--> Sending: ATDT#777
--> Waiting for carrier.
ATDT#777
CONNECT 230400
--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Wed Aug 12 18:08:43 2009
--> pid of pppd: 31981
--> Using interface ppp0
can you help me? Thank you.

Isn't it? Why does select function wait for forever even that I add
the line: self._timeout = 5 before "ready,_,_ = select.select
([self.fd],[],[], self._timeout)" ?

E200...).

In the Google, I find the AT command to send message:
http://www.unpackstudio.com/printer_friendly_posts.asp?TID=1
AT$HSMSD=<PH>,<LENGTH>,0,1
the command is strange, how can i enter the message text ?
Thank you for the Pyhumod. Do you have the at commands with EC325 or
EC321?
And how can i use the ppp connect function in Pyhumod ? Because when I
enter:
>>> m.connect()
File "<stdin>", line 1, in ?
in connect
data_port.send('ATZ\r')
File "/usr/lib/python2.3/site-packages/humod/humodem.py", line 154,

My apologies for a very late answer, I was on 3-week holidays with no
access to Internet.
I tried to get hold of EC325 but, unfortunately, none of my friends
was in a possession of the device, so I can't really confirm if a
different set of commands applies, but I suspect it shouldn't be much
different from e.g. E220.
In your first posting you mentioned that you were using an outdated
Linux version issued in 2005 with an even older dbus subsystem (which
is probably a reason why find_huawei_iface.py fails). Can you please
try something more recent?
It seems that the modem device (/dev/ttyUSB0) is recognized correctly,
but the control device (/dev/ttyUSB1?) does not allow serial port
communication and hence pyhumod hangs forever on it.
Please try the following, it would be best if you could answer the
questions on some recent Linux distribution (with a kernel issued at
latest in 2008):
What is the output of 'ls -al /dev/ttyUSB*' command?
Do you see 2, 3 or more ttyUSB* interfaces?
Use minicom to connect to the ports that have been listed and try
typing in the minicom window the following command:
AT+GMI <press enter>
AT+GMM <press enter>
They should display the manufacturer and device model on the ttyUSB?
ports that are correctly recognized.

Thank for your message.
first, In my RHEL 4.2, I got the error message:
File "find_huawei_iface.py", line 74, in ?
main()
File "find_huawei_iface.py", line 64, in main
devices = find_huawei_devices()
File "find_huawei_iface.py", line 42, in find_huawei_devices
hal_mgr_obj = bus.get_object(BUS_NAME, MGR_OBJ)
version of dbus is too old.
second, I try my best but I can't find the reference of EC325. But
in the end I find the at commmand of EC325. the url is:
http://www.sangrong.com/download/cm300.pdf
I have test the AT command of send message, ppp connection and
telphone number. It successes. I think it may be useful for you. Then
I will try to change your pyhumod to send message, visit the wap site
through ppp connection etc. It will be a large work for a junior.
Thank you again for your code.

then we can send all at commmand with this interface.

I understand that the question is why I didn't implement that function
or method.
This is where a developer guide would come in handy - I will try to
publish something on the project wiki this weekend.
Anyway, I implemented something else - the Command class.
Here is a short description of how it works:
In general, you can pass an AT command to the modem in 4 ways:
- "AT+CMD" - to tell the modem do something, (run)
- "AT+CMD?" - to query the current setting in the memory or the
current state, (get)
- "AT+CMD=?" - to see what are the possible values to set, (dsc for describe)
- "AT+CMD=value" - to set a value for the given command/setting. (set)
For instance, if you want to see who is the manufacturer and use an
"AT+GMI" command to do that you can do the following:
>>> import humod
>>> from humod.at_commands import Command as Cmd
>>> m=humod.Modem()
>>> show_manufacturer = Cmd(m, '+GMI')
>>> show_manufacturer.run()
If you want to get a list of networks with the "AT+COPS=?" command,
you will do the following:
>>> networks = Cmd(m, '+COPS')
>>> networks.dsc()
and so on...

In the huawei AT Command: http://www.sangrong.com/download/cm300.pdf
Send message command is : AT$HSMSSD=13300133110, 11, 1, 1
it will be sure that I can't send message with function "dec". I
suggest that you would make a moderm class： it acts like the command
minicom. After connecting I enter the whole AT command and the result
returns.
I find the similar perl package in the CPAN.

I think it is useful for you. Thank for your code.

I can't disagree with the fact that there is a bunch of problems in my code :)
However, the functionality that you are looking for is probably
already in there. You can use one of the serial port methods
(inherited from serial.Serial) to send strings to the modem
minicom-style.
For instance:
m = humod.Modem()
m.ctrl_port.write('ATZ\r\n')
Also, it's not the dec() but dsc() method. And I agree, you can not
set values with the dsc() methods (dsc is there for querying). You can
do it with the set() method. Just in case you would like to do that I
have redesigned some of the internals and updated the Developers
Guide:
http://code.google.com/p/pyhumod/wiki/DevelGuide
Obviously, I'm not stopping you from hacking PyHumod minicom-style.
Please make sure that you use the latest source version from the
mercurial repository.

Thanks for the link.
It's probably a good idea to close this thread as it went a bit off topic.
