Open connection at 9600 8-n-1 and type "AT" and hit enter.
you must get a reply "OK" from phone. test it!]]> contact@nospam.com (Ajay Bhargav) Sun, 09 Mar 2008 08:41:02 -0700 http://www.8051projects.net/forum-t6734.html Re: Cammand with GSM (PIC16F877) http://www.8051projects.net/forum-t6734.html my mobile Siemens C45

and I tried an exemple with isis simalation and it works properly
but when I tried with pic in the real carte and i connect the GSM dierectly to RX and TX withe pic it doesn't work so how to connect GSM withe PIC
pleas help me
thank you.
