What steps will reproduce the problem?

using datacard k3520, k3765 and E1752 in the same usb hub. After load 
chan_datacard.so, we have

What is the expected output? What do you see instead?

1 k3520 disable call waiting without problems, but the other one, and also 
k3765 and e1752 fails

What version of the product are you using? On what operating system?

using r59 on debian squeeze

Please provide any additional information below.

AT+CCWA?

check call waiting status, not enable or disable this feature.

AT+CCWA? executed long time because ask network for value.

may be gsm still not registered  at time of AT+CCWA?

I try move CCWA setting and status checking to moment when GSM registration 
done.

Also in r70 errors in response of AT+CCWA= AT+CCWA? not cause disconnection 
from device.

just seen that after module unload chan_datacard.so and module load 
chan_datacard.so... I have some 

[Dec  4 17:58:42] ERROR[6181]: at_response.c:329 at_response_error: [datacard3]

but not causing disconnection from device...

check debug output for device responses, may be device really response ERROR on 
AT+CCWA=1,2,1 or chan_datacard can't parse response

also how has command
CLI> datacard callwaiting enable|disable device

instead of 'datacard ccwa'

GoogleCodeExporter commented 9 years ago 
Heh, call waiting is service provided by network, may be some networks not 
allow this completely?

Not very important, but still a bit messy

Enable debug
core set debug 5

edit logger.conf for debug save to file.
and check commands and responses 
looks like 
[Dec  3 16:41:21] DEBUG[9904] at_queue.c: [datacard0] write command 'AT+CLIR' 
expected response 'OK' length 10
[Dec  3 16:41:21] DEBUG[9904] at_queue.c: [datacard0] [AT+CLIR=2
]

[Dec  3 16:41:21] DEBUG[9841] at_read.c: [datacard0] receive 6 byte, used 6, 
free 4090, read 0, write 6
[Dec  3 16:41:21] DEBUG[9841] at_read.c: [datacard0] [

]

logs looks good, if registration process done 
and device said 'ERROR'  i would hardly help that :)

AT+CCWA=1,1,1
OK
enable call waiting for voice 

AT+CCWA=1,2,1
ERROR
can't check call waiting status for voice

but next i see AT+CCWA=1,1,1 and AT+CCWA=1,2,1 is ok response.

Its on same device?

I think it could be a problem from network operator... I'm using Virtual Mobile 
Operator and the behaviour is a bit random on two different locations...

by the moment, if nobody reports any additional error... I think this should be 
closed.

thanks
