I have IR Remote of 21 buttons 0-9 and vol up-down, power on-off etc.

Please let me know that how to know the codes it transmit.

Any software for read IR remote codes.
 

Each manufacturer has its own codes for controlling their line of appliances.

There are all-purpose remote controls available. These have index lists in the back, with brand names and codes which you must punch in, so you can make the remote work with your equipment.

There are also 'learning' remotes which pick up an infra-red signal from the first remote, and copy it.

You will need an oscilloscope to observe the various high and low pattern of flashes which come from the led.

Each command consists of numerous high/low pulses... so many that it is hard to distinguish one command from another.
