Two questions about cu on Red Hat 6.0/Mandrake 6.0
* It insists on /dev/ttyS0 being world-writable, else it complains
"permission denied; line in use". crwxrwxr-x won't do, even though
its owner is root, group tty. Any way of having more restrictive
permissions there?
* I can set even parity (-e), I can set the use of a stop bit (--nostop).
Can I set it to use 7 data bits instead of 8?
Cheers,
Dave
