- Also, the terminals needn't be directly connected to the host,
- or even owned by the same organization as the host (thus the
- capabilities of the fancy terminal may have no relevance for, or
- its owner may have no influence on, the gateway host software).

- I'm personally not too bound to 8 bits as the ultimate data unit
- size. Today's efforts of 'stomping out' 7-bit transmission
- channels for being obsolete in the presence of superior *8-bit*
- channels (even as it's probably a good idea) may seem amusing
- sometime in the future, when 8 bits have likewise been stomped
- out in favour of 16 bits, or whatever is the fashion. So, I
- prefer not to be too quick labelling every 7-bit application as
- 'buggy' today, especially when they weren't yesterday.
-
- What? Are there *still* 8-bit processor architectures out there
- in the suburbs? ;-)
-
- What we really need is to separate the application issues from
- the transport issues. The application writer (or the user) need
- not, and *should* not, care about how the lower layers of the
- communication medium are implemented. The user may have specific
- demands in terms of speed and functionality, but it shouldn't
- matter to me whether this article is transported via an 8-bit
- channel, a 7-bit channel, a deck of punched cards on a jet plane
- or whatever, if it just reaches its destination unmodified and
- within reasonable time. By allowing the lower layers to pick
- any communication channel they like, the best performance is
- achieved. Ask DHL...

- Haven't people studied the OSI network reference model?
