detect process attached to devices

Hi All,

How to find the process's that were attached to devices. For example, if we open ttyS driver from user space application, is it possible to get the process id by examining the /proc of the devices? If yes, how?

Thanks in Advance

You can use lsof to find the PID of the process that uses the serial port:

Code:

lsof|grep ttyS

Then under /proc/<PID> you'll find more details about that process.
