I've also seen more than one byte missing. For example when sending a big chunk of bytes down the pty via an Emacs *shell* buffer up to 16 bytes are missing somewhere in the middle. > Does the problem go away if you change the default value of "chunk" (in > drivers/char/tty_io.c:do_tty_write) from 4096 to 2048? Yes, that helps.
