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 |
