I am trying to send Ericsson T28s AT commands while working in my graduation project in Microcontroller
but i can not type any thing in the window of HyperTerminal !
i have attached a picture of the Hyperterminal , its a program in the windows XP accessories ,
how can i type in it commands
i have connected the RS232 cable , and set the COM , the BIT rate and everything
HELP ME PLEASE
THANKS
Because it runs so called "silent" coursor.
But whatever you type it is sent out as ASCII ..
If you want to know what you are sending download a terminal software and compose your strings which will be sent out by clicking on certain buttons.
Termnal software you can download from:

I have installed the (RFI interm terminal ) but when i type any AT command to Ericsson T28s , there is no response !
i have attached a picture of the screen of the program while i tried to type AT commands
How to set this program to work with RS232 9 pens serial port ? how to get response from the mobile ?
please help me
Finally i have figured that all the terminal programs are the same , i have downloaded more than 3 terminal programs and all of them are same , i have successfully load the correct COM and its settings , but when i type a simple comand like AT or ATZ or AT&F theres a response , but the problem is in the long commands like AT+CGMC=?
i have attached a picture please see it and help me please to get the correct form of typing the commands
thanks
