Hi,
I am using cdc-acm driver on Linux with kernel 2.6.16.13 for my Sony
Ericsson Z1010 mobile.I connected the mobile to the Linux pc and tried
sending sms using AT Command Interface of the mobile.What I have
observed is that when the size of the sms pdu is greater than 64
characters sms is failing.I suspect the problem could be that the
cdc-acm driver is allowing to write only upto 64 characters.Is there any
possibility to write more than 64 characters at once.Pls let me know.
Here is my device configuation from >cat /proc/bus/usb/devices
