The driver was much changed in System III; the "IXANY" bit was not in any other UNIX terminal driver. Specifically, it is not in the V7 driver. Berkeley's "V7 with goat gland injections" driver has a bit which is the inverse of this, called LDECCTQ. As such, "stty -ixany" doesn't do a bit of good to a user running V7 on a Perkin-Elmer 3220, and patching source code *is* required to make XON/XOFF handling strict on that system. Please don't assume that everybody is running your version of UNIX. Also, if you *are* asking a question about UNIX, please state the derivation of the version; it will help people to give you an answer pertinent to that version.
