- Suggested Telnet Protocol Changes
-
- I hereby propose the following changes to the Telnet protocol. If
- no substantial negative response is received by 15 May 72 it will be
- assumed that these changes are desired and should be incorporated in
- any "Official Telnet Protocol".
-
- First I suggest that we drop the idea of a "minimum"
- implementation and require a standard implementation which includes all
- aspects of the protocol.
-
- Second I suggest that we eliminate the DATA TYPE signals.
-
- Third I suggest that we do away with HIDE YOUR INPUT signal.
-
- Arguments:
-
- Standard Implementation:
- The idea of an accepted implementation which does not include
- whole protocol is an admission that the parts of the
- protocol left out are either not useful or not expected to be
- used, and that other mechanisms will be constructed to provide
- those functions. Thus there should be no minimum
- implementation, but only the standard implementation which
- includes the whole protocol.
-
- Data Types:
- The DATA TYPE signals are supposed to allow the communicating
- processes to switch from ASCII to some other code set. However,
- the other code sets suggested do not allow for the Telnet
- signals, and thus once the switch is made the Telnet
- protocol is no longer applicable. There is no way to specify
- how to get back to ASCII or Telnet thus the
- conversation is "out of control".

- Hide Your Input:
- The HIDE YOUR INPUT signal is supposed to tell the user Telnet
- process to do whatever it can to hide the user's
- subsequent input. One problem with this is determining
- how much input is to be hidden. It is very difficult to find a
- method of hiding input which works for all combinations of
- systems and terminals, but the HIDE YOUR INPUT signal dosen't
- help in any real way.
