How to open ttyS3 in AT9aSAM9260? - pratibha_275 - Jul 7 2:43:55 2009
Hi!
Actually i want to use an extra COMPORT in AT91SAM9260.
Lie my ttyS1,ttyS2 ports i am not being able to open ttyS3 as i have mknode it in my /dev folder but still i am getting an error message
"/dev/ttyS3: No such device or directory ".
I think the driver should be the same for all the ports.Is there any other thing to do? What should I do?

Hi,
Do you have geTTY daemons running for those ports ?
In any case, just creating the dev won't "create" new tty ports.
