Question Using serial port in T720i


Hello,

I am working in a project that needs to use one barcode reader connected to celular by serial port or USB.
I am using a program in Java to receive this data and the terminal choosen,following instructions, was Motorola T720i, and I am using RS-232.
According Motocoder instructions, to do it works I need to :
- open connection in Java
- send from device
AT
At+mode=19
I emulate this in two ways:
1) using hyperterminal
2) wroting a program to do this from PC
( I am sure that cable is working fine, since I received answer from At commands )
But after send the last command ( I can heard one sound in the celular side ),
in both cases I can't send anything more ( hyperterminal freeze ) or either get anything in Java side.

Does anyone know what I need to do ? What is wrong ?
( I am thinking that may be that this model cannot accept this kind of implementation - If it is right, is there other celular phone that I can do this ? )

Regards

Paulo S
