Hmm yeah looking at my notes I also had some issues and did something like
this to install git version of phone gem:

$ git clone git://github.com/carr/phone
$ cd phone
$ sed -i 's/beta//' lib/phone/version.rb
$ cd phone
$ sed -i 's/1.3.0.beta1/1.2.9/' lib/phone/version.rb
$ gem build phone.gemspec
$ sudo gem uninstall phone
$ sudo gem uninstall bigdecimal -v 1.4.2 # 1.3.4 works
$ sudo gem install phone-1.2.9.gem

Yeah the scripts in droid4-sms-tools git repo work for me for sending
and receiving. They do not work with cdma currently as the format is
different.

Maybe you've managed to change the mode of the modem to queue the
messages with the at commands to the usb port?

You are reading and writing to /dev/motmdm9 for incoming sms right?

I think AT+GCNMA=1 works 3g and AT+CNMA=0,0 with cdma. Or it could be
that one of them is just a delayed ack, I don't know.

Regards,

Tony
