Yes. The case I tried was a large write (strace cat /etc/somefile > /dev/ttyDA2) and strace showed a single large write, but it got to the driver in chunks of a dozen or so characters. Is that expected to happen?
Yes it is - the tty mid layer code could do better on this but it's never been much of a priority.
