Hello..

It's kinda strange though but I am getting a permission denied when I
try to read from the /dev/ttyd0 device although I have:

crw-------  1 root  wheel    0,  75 Jul  1 20:49 /dev/ttyd0
crw-------  1 root  wheel    0,  76 Jul  1 20:45 /dev/ttyd0.init
crw-------  1 root  wheel    0,  77 Jul  1 20:45 /dev/ttyd0.lock

I'm running the command minicom and here is my minicom configuration


lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk
    x A -    Serial Device      : /dev/ttyd0

Any idea what could be the reason?
