what is major number and what is minor number..?

Answer Posted / vijay

The driver knows the minor number of a particular device..
For example, the major number of pts is 136..
Assume, we have three pts.. So, the major and minor number
will be as follows..
Device Major number Minor number
pts/0 -> 136 0
pts/1 -> 136 1
pts/2 -> 136 2

Whereas, the Kernel identfies the device using the major
number..
