Hi

I have to access a device through serial port . that device sends some
messages per second that needs to be received . I am

that what
should be better option either to wait in select system call or
checking input buffer through ioctl (..FIONREAD) periodically at some
100ms ? can any body have any idea regarding this ?

I use select(2) no need to anything to see if data is available. (no busy waiting)
works for me.
