-
- I beg to differ. THE standard network adapter interface is the one
- in most use. Novell's officially endorsed standards and PDI probably
- put NDIS in third place.

- Not so, drivers for half the cards I own were not there. Instead it
- was necessary to play for a few hours with files downloaded from 3com
- and manually edit the scripts. I tried it the official way, but it
- didn't work.
-
- And remember, I'm no hick to the subject, I have installed, used and
- programmed for most PC implementations of TCP and written my own and
- of course done the unix thing under many different brand names.

-
- Protocol adherance isn't proven by just telnetting into a few Unix
- systems. There are many non-unix systems and it becomes an n-complete
- problem to tackle it that way. But there are some some carefully crafted
- conformance testers which look for common bugs. One such system
- is available somewhere on netlab.usu.edu, but I don't remember the name.
-
- BTW, people who write the core terminal driving software often avoid
- using all the escape sequences available to them because many VT emulators
- are broken in various ways. Instead the typical situtation is to
- select a few core sequences and loose slight efficiency but at
- the benefit of increased compatibility with broken implementations.
- I know this because I have implemented a few TELNET daemons and
- have had to accomodate loose or broken emulators.
-
- The comparison I keep hearing in the defense is how much simpler or
- nicer it is compared to Unix. But remember, it is competing in the
- DOS/Windows/NT classes, not Unix.
-
- I don't want to come off as suggesting IBM TCP is crap. ICAT works
- well for installations, the core applications are there and I believe
- third party apps will make up the difference. But don't expect this
- TCP to offer utilities which look as nice as some of the windows
- counterparts or even many of the freeware products such as NCSA
- TELNET or match the flexibility of MS-Kermit.
-
- It's only when you look to IBM's extensions (extra $) for X or
- NFS that you get a clear advantage over running freeware DOS
- apps in a DOS VDM.
