Are you using hyper terminal?

[lqq889]

yes, i am using hyper terminal..

At that morning, i tested the BRM module by sending some of the commands like "local name(K)"
it responsed, it works.

Next, i saw the Local name of the module(Sensor 5 Temp) was not i want, so i press switch button(SW1) on the module, the command line menu(CLM) appears, i choose option 1(Setting) and next choose 4 (Local Name), after that i enter some of the names but because it shows 1 or 2 unknown charaters ,so i change it quite a lot times.
The names that i entered something like:Greeny Robot0x00(16 characters),(3 spaces)Greeny(2 spaces)Robot... Finally, i found a name that i want.
i quit the CLM, and switch off the power a while and switch on again, i press SW1 go to CLM ,choose 1 and saw that :
Menu 1 (Settings) Choose an option:
1 = Normal----->minivoice
2 = GPIO Mode On-------->GPIO Mode Off
3 = BAUD Rate 115200
4 = Local Name
5 = Idle Timer Off
ESC = Back

i changed it back to normal, and switchede off again, after a few minutes i switched on and test it with my programs, it can not response to its commands and i try it on the hyper terminal, it shows the same thing as what program does.

So please try to help me to solve this problem , thanks very much for your kindness.
