Which Linux kernel ? In 2.4.20 :-

./include/linux/tty.h:153:#define PTY_BUF_SIZE	4*TTY_FLIPBUF_SIZE
./include/linux/tty.h:137:#define TTY_FLIPBUF_SIZE 512

Which means 2048 not 155. Is the limit some other place, libc or is
yet another Redhat x.0 screw up ?

On my machine, 2.4.20 glibc 3.2.1 it is definitely 2048 as I have a
perl module based upon Expect where each read and write of a big
transfer through the pty receives/sends 2048.
