Hi every body!

I have some problem with Nokia 6020, I open hyper terminal with setting (9600,8,N,1,N),(19200,8,N,1,N),(115200,8,N,1,N) and send "AT" command but no respone.

If I install nokia connecting, and use connect managament to connect Nokia, after that disconnect and connect again with hyper terminal with (9600,8,N,1,N) and send "AT" command, it respone "OK", but I turn off power of phone and open again, the same problem. Can you help me?

Best regrads,
Manh
