stdout to console

Hello Guys, We all know that when an application writes to stdout, data ends up in the console. Okey so if I m on my development board and if I run an app, all the prints comes to the console (eg /dev/ttyS0). If I m on any server using ssh and all apps prints comes on my putty (eg through /dev/pts/176). Where is the code which maps fd 1 to the console in kernel? If you guys have any pointers, please share. While opening a device (for eg /dev/something), the vfs calls that drivers, whose major and minor number matches. But in case of stdout, how vfs resolves the write to the fd 1 and send it to the corresponding console driver? Thanks, Arun
