How to access the second serial port

cheema · 07-28-2004, 05:27 AM

Hi,
I have a net-arm board which has 2 serial ports coming from the processor. But in the default linux image provided along with the board only tty and ttyS0 devices are visible in /dev directory. The second one is left to be configured by the user. How can I access the second serial port? Do I need to write my own tty driver. I have been looking through some tty drivers but have not been able to locate how to specify the port number of serial port.
Any help in this regard will be greatly appreciated.
