but the problem how to access the data from the sd card into the serial port ,
please help if there any idea .
thank you .
 

To interface sd card with microcontroller 1st thing is to choose a correct microcontroller another thing is you must know the uses of serial communication. Directly you cant interface sd card to mc via serial communication for interfacing sd card you should go for SPI communication and access through it and send data via serial port. Mostly 8051 does not available with SPI
