Serial Port

29 de Mayo del 2006

I need to make some code to connect my laptop with a USB device to send some AT command and receive the response. I am trying the SerialDemo application and it opens the COM port and write what I put on the "OUT" panel. But nothing appears in the "IN" panel...

I can send and receive with the Hyperterminal, so the USB device and the COM port work fine, but not with the java code.

Any idea?

Thanks in advance
