Subject: error opening /dev/tty1 on cygwin

Hi,

I tried to open /dev/tty1 on cygwin and got an error. Here is my code:

         fd = open ( "/dev/tty1" , O_RDWR | O_NONBLOCK );
         if (fd < 0)
         {
                 perror("io_rs232:: open");
         }

I did not find the directory /dev on cygwin but ls -l /dev/tty1 works fine. 

> ls -l /dev/tty1
crw-rw-rw-    1 Everyone Everyone   5,   1 Sep 11  2001 /dev/tty1

Can anyone provide me with a solution to this problem?

Thank you.

Regards,
Vishnu.
