The problem with the Nokia phone which I'm using (Nokia 5110) and all older phone is that they do not understand AT command set directly, Here is the command set. (http://webapp.etsi.org/key/key.a...Part2=007)
If you have to use these AT commands then you need a piece of software called Nokia Data Suite which will allow you to talk to phone using Hyper Terminal. Without these software you can not directly connect to phone and supply AT command like some other phones which have a Hardware phone builtin. So I tried Snooping the communication which happens between Phone and PC in portmon and then using a 8052 Simulator I wrote above program. This is something which everyone on the list is asking for directly or indirectly. Please I'm new to 8052 and assembly the code which I wrote is picked up from various code sample. I know how the nokia software talks to phone but I'm not able to emulate samething using 8052 Simulator, please help. I'll release whatever I'm able to achive under GPL.
Thanks.
