Code:
FreeBSD 8.0-RELEASE GENERIC amd64
Code:
# stty -f /dev/cuaU0
speed 9600 baud;
lflags: -icanon -isig -iexten -echo

cflags: cs8 -parenb -hupcl clocal cstopb
min time
200 1With 9600 baud 200 bytes takes longer than 0.1 seconds.
However, read() returns after 0.1 seconds with less that 200 bytes.
Somehow it seems that the time above is not an inter-byte timer (as it should be),
but rather a read timer (after the first byte is received however).
This is not a big issue. By using 5 instead of 1 my application is happy.
Merely I'm just wondering why FreeBSD works here differently than NetBSD.
Or maybe I'm messing around by myself.
It is a VIA 83C572 USB controller.
