i'm trying to one project my own interest using p89v51RD2 muc i have one problem my project is GSm based so my code working well on keil while debugging, but when burning on chip it's not working , actual problem is one receive and transmit complete after clear buffer and i value then next receive data is "miss match" then after clear i value and buffer then next receive data is "match" then one transmission complete next receive data will be "miss match" i'm using flash magic for burn in chip. that's my problem

i'm trying to one project my own interest using p89v51RD2 muc my problem is first receive char stored buffer then compared with already stored(globally) value if it's true then do some process like number store function(add(),password change function(chpwd()etc, it's all done perfect, then "acknowledgment" get from micro controller(p89v51RD2) through sms ( send_sms5();,send_sms1();,ect,,) also done next another process again receive char it's not compare that means miss match( glowing red LED),then do again this process (receive char) it's working done then get "acknowledgment" through sms is done, then another process again receive char it's not compare that means miss match( glowing red LED), it's repeat again again one "acknowledgment" get from mc next receive char miss match,

" if "acknowledgment" through sms replaced only LED glowing for acknowledgment it's all working fine, so any transmit from mc then receive char were store in buffer that's problem, how can rectify that ...?
