 I looked at the dcm man page, and the makedev script, and they both
state that i should be able to use the dcm ports as tty00-tty0f (16

 However, when i do a 

cu -l tty00, i get a permission denied. Just today on the sparc list,
someone has the same problem. I changed the permissions, and with the same

What is strange, (to me at least) is that cu -l tty0 works fine. That is
the rs-232 port.

So, looking at the dmesg output, is there anything i am doing wrong? The
power light is on my 8 port MUX. Since i have to dcm cards, i have tried
in both of them, the result is always the same, for all tty0X.
