TELNET OUTPUT VERTICAL TAB DISPOSITION OPTION

1. Command name and code

NAOVTD 15

(Negotiate About Output Vertcial Tab Disposition)

2. Command meanings

In the following, we are discussing a simplex connection, as

described in the NAOL and NAOP Telnet Options specifications.

IAC DO NAOVTD

The data sender requests or agrees to negotiate about output

vertical tab character disposition with the data receiver.

In the case where agreement has been reached and in the

absence of further subnegotiations, the data receiver is

assumed to be handling output vertical tab character considerations.

IAC DON'T NAOVTD

The data sender refuses to negotiate about output vertical tab

character disposition with the data receiver, or demands a

return to the unnegotiated default mode.

IAC WILL NAOVTD

The data receiver requests or agrees to negotiate about output

vertical tab character disposition with the sender. In the

case where agreement has been reached and in the absence of further

subnegotiations, the data receiver alone is assumed to be

handling output vertical tab character considerations.

IAC WON'T NAOVTD

The data receiver refuses to negotiate about output vertical

tab character disposition, or demands a return to the unnegotiated

default mode.

IAC SB NAOVTD DS <8-bit value> IAC SE

The data sender specifies, with the 8-bit value, which party

should handle output vertical tab characters and what their

disposition should be. The code for DS is 1.

IAC SB NAOVTD DR <8-bit value> IAC SE

The data receiver specifies, with the 8-bit value, which party

should handle output vertical tab characters and what their

disposition should be. The code for DR is 0.

3. Default

DON'T NAOVTD/WON'T NAOVTD

In the default absence of negotiations concerning which party,

data sender or data receiver, is handling output vertical tab character

considerations, neither party is required to handle vertical tab

characters and neither party is prohibited from handling them; but

it is appropriate if at least the data receiver handles vertical tab

character considerations, albeit primitively.

4. Motivation for the Option

Please refer to section 4 of the NAOL and of the NAOVTD Telnet option

descriptions.

5. Description of the Option

The data sender and the data receiver use the 8-bit value along with

the DS and DR SB commands as follows:

8 bit value Meaning

0 Command sender suggests that he alone will handle

vertical tab characters, for the connection.

1 to 250 Command sender suggests that the other party alone

should handle tab characters, but suggests that a

delay of the indicated value b...
