- Because UUCP is distinctive among UNIX applications in having "secrets"
- buried inside it. To be a UUCP a utility should, at a minimum, be able
- to communicate successfully with at least some large proportion of all
- existing implementations; unfortunately, the protocol isn't documented
- for potential implementors. The only reasonable way to get the protocol
- is to read the source code; this makes your resulting implementation a
- derivative work and therefore AT&T proprietary. It is *not* appropriate
- to produce a standard mandating something which is strictly AT&T
- proprietary.
-
- Actually, I have heard of one (1) instance of a UUCP being written and
- not beholden to AT&T. However, with substantially less effort than is
- required to work from a line trace up and reverse engineer the protocol,
- you can produce a complete replacement that works far better in several
- important respects (e.g. built-in quoting to enable transparent
- transmission through 7-bit communication channels, support for various
- flow control mechanisms including the terrible XON/XOFF, ability to work
- efficiently in the face of long round-trip packet delays and/or half
- duplex, logon dialog specification far more flexible than "expect-send
- strings", and so forth). If you want the ability to intercommunicate
- with arbitrary other UNIX systems, write a host end portably.
-
- Let's not go out of our way to put roadblocks in the way of competition;
- AT&T already isn't the only source for substantially UNIX-like operating
- systems; they aren't the only ones who could make available a POSIX
- compatible operating system, if gratuitous obstructions like UUCP (with
- its undocumented protocol) are avoided.
