+Avoid hang of serprog under FreeBSD
+
+Use case is flashrom+serprog to read SPI flash (MX25L6406) via Arduino
+Nano V3.  Actual command is:
+
+/usr/local/bin/flashrom -p serprog:dev=/dev/cuaU0:57600 -c MX25L6406E/MX25L6408E -r tcw770.dump
+
+Using flashrom 0.9.9 it hangs after 5 seconds on read from tty ("ttyin").
+The problem is that kernel method "ttydisc_rint" ignore same bytes.  It
+happens due to enabled IEXTEN local flag of termios.  TTY cuts few bytes,
+Arduino reads 11264 bytes, but flashrom gets 11244 bytes (corrupted) and
+waits for remaining 20 bytes.
+
+The fix is simple: turn off IEXTEN local flag.
