AT commands through matlab to my mobile

[Rufiorocks]

its working fine with the hyper-terminal.i can send msg and get "ok" command when i type "at" at hyper terminal.

but in matlab:-

s = serial('COM12');
set(s,'BaudRate',9600);
fopen(s);
tx='AT';
fprintf(s,'%s',tx);
out = fscanf(s)
fclose(s)

as suggested by one of the members in previous posts i tried the above code
it is not working
either i get 'out= AT'
or ' out = " ' (i.e. Warning: A timeout occurred before the Terminator was reached. )

what should i do plz guide me

i also tried with tx='AT\n' even this doesnot work

Try this then we will see:

s = serial('COM3');
set(s,'BaudRate',9600);
fopen(s);
tx='AT+CMGS="xxxxxxxxx"';
// where xxxxxxxx mobile number and AT+CMGS protocol to send sms by mobile
fprintf(s,'%s',tx);
a = 'ss';
fprintf(s,'%s',a);
fclose(s)
delete(s)
clear s

i tried what u gave me to try....
also i tried to follow the same steps as i did in hyperterminal

s = serial('COM16');
fopen(s);
set(s,'BaudRate',9600);
tx='AT+CMGS="xxxxxxxxx"';%mobile nunmber
tz='AT+CMGF=?';% wanted to do exactly as i did in hyper terminal
tq='AT+CMGF=1';% so took followed these steps
a='ss';
fprintf(s,'%s',tz);
fprintf(s,'%s',tq);
fprintf(s,'%s',tx);
fprintf(s,'%s',a);
fclose(s);
delete(s);
clear s;

but neither matlab is showing any error nor any msg is being sent...no reaction
i tried to use fscanf(s,'%s') and fscanf(s) but its giving a warning as "Warning: A timeout occurred before the Terminator was reached."

This sounds like some Bug!

Try to restart all and try again.

@tpetar just for the thought .. when we use a hyper terminal we press ctrl+z at the end...but while programming the port from matlab we dont send ctrl+z..is there any connection??

i have one more doubt.....we are using command "serial" for accessing my mobile but my mobile is actually connected by a USB to my cell phone..so how will it work for s=serial('com12');
plz help..
