GTA02 modem port messed up

[Sean McNeil]

I have some issues with the latest stable-2.6.26 and the modem. It is 
acting like some sort of block device. It takes several commands before 
I suddenly get a response from each. For instance,

ATZ
ATZ
ATZ
ATZ

then finally after a number of them, they get echod:

ATZ
OK
ATZ
OK
ATZ
OK
ATZ
OK

How to repeat:

follow steps in twiki for manual use of GSM.

cu -s 115200 -l ttySAC0
in another shell,
stty -F /dev/ttySAC0 crtscts

Has anything been done with the flow control on GTA02? I would consider 
this high priority.
