Status: AT2 module fails to open serial ports after system startup

There is still this problem,
but I'm sure sometimes ago (about 8 months) there wasn't even
on at2, non mentioning that in at there isn't.
I looked into the code, and the at2_test_speed
could not get an OK when sending AT (3 times)
When you use minicom or Hyperterminal, on the first command
you have an error but after that you receive an OK.
Anyone who wants to try to solve this problem? Oded, have you
done any step further to solve this problem inside the at2 code I mean,
not the 
stty -F /dev/usb/tts/0 1:.... in the STatus.

Thanks

Andrea
