To add a bit of information to the thread and the essentially correct responses, you can check out the manual pages for ‘stty’ and ‘sysctl’ (with the “man” command, as in “man stty”).  See the blurbs under “stty -imaxbel” and “man sysctl user.max_line”.

Keep in mind that the man pages in unix/linux systems are not always completely accurate, but they will give you an idea of what is/should be happening behind the curtains.

In short, the issue is a system one, dictated by how it handles buffers and buffering in the kernel.
