Dear Otto:

You might check that the dev entry points in your root file system for =
/dev/tty, /dev/console, /dev/ttyS0 and /dev/ttyS1 all exist. They must =
be created with mknod and not with mkdir.=20
=20
These are the settings you should see with an 'ls' of the target's root =
filesystem on the host which has created it. All of these entries should =
be character devices as shown by the first bit of the permissions being =
a 'c'.

/dev/console 5 1
/dev/tty 5 0
/dev/ttyS0 4 64
/dev/ttyS1 4 65

Subject: ttyS0 ttyS1



Hello,
i have problems to use ttyS1 on my TQM885 Board.

fd1 =3D open("/dev/ttyS0",O_RDWR);
fd2 =3D open("/dev/ttyS1",O_RDWR);

I have expected to get different filehandles, but
both handles for ttyS0 and ttyS1 are 0!

Any help is very appreciated.
