- How? I assure you that ISTRIP (or its equivalent) is not getting
- mysteriously turned on on any of the systems I use; my terminal uses
- an 8-bit binary packet protocol and I have never seen it broken by a
- sudden shift into ISTRIP mode. If your system has such a bad bug,
- you should get the bug fixed rather than rail against the availability
- of an often-useful feature.

- Yeah, standards are funny that way.

-
- Basically, it was one of numerous tty handler capabilities provided by
- the standard implementation on which the 1003.1 specification was based;
- there are several of these (ioctl bits) that aren't widely useful; if
- they don't meet your needs then you should feel free to not use them.
- Generally, the interface bit rate, framing, parity, etc. should not be
- altered by applications; they should be left exactly as established by
- the system agent that established the tty port connection.
