Telnet Output Carriage-Return Disposition Option

1. Command name and code

NAOCRD 10 (Negotiate About Output Carriage-Return Disposition)

2. Command meanings

In the following, we are discussing a simplex connection, as described in the NAOL and NAOP Telnet options.

IAC DO NAOCRD The data sender requests or agrees to negotiate about output carriage-return 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 carriage-returns.

IAC DON’T NAOCRD The data sender refuses to negotiate about output carriage-return disposition with the data receiver, or demands a return to the unnegotiated default mode.

IAC WILL NAOCRD The data receiver requests or agrees to negotiate about output carriage-return 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 carriage-returns.

IAC WON’T NAOCRD The data receiver refuses to negotiate about output carriage-return disposition, or demands a return to the unnegotiated default mode.

IAC SB NAOCRD DS <8-bit value> IAC SE The data sender specifies, with the 8-bit value, which party should handle carriage-returns and what their disposition should be. The code for DS is 1.

Telnet NAOCRD Option Page 2

IAC SB NAOCRD DR <8-bit value> IAC SE The data receiver specifies, with the 8-bit value, which party should handle carriage-returns and what their disposition should be. The code for DR is 0.

3. Default

DON’T NAOCRD/WON’T NAOCRD. In the default absence of negotiations concerning which party, data sender or data receiver, is handling output carriage-returns, neither party is required to handle carriage-returns and neither party is prohibited from handling them; but it is appropriate if at least the data receiver handles carriage-returns, albeit primitively.

4. Motivation for the Option

Please refer to section 4 of the NAOL and of the NAOP Telnet option descriptions.

5. Description of the Option

The data sender and the data receiver use the 8-bit value along with the NAOCRD SB commands as follows:

8-bit value Meaning

0 Command sender suggests that he alone will handle carriage-returns, for the connection.

1 to 250 Command sender suggests that the other party alone should handle carriage-returns, but suggests that a delay of the indicated value be used. The value is the number of character-times to wait or number of NULs to insert in the data stream before sending the next data character. (See qualification, below.)

251 Not allowed, in order to be compatible with related Telnet options.

252 Command sender suggests that the other party alone handle carriage-returns, but suggests that they be discarded.

253 Not allowed, in order to be compatible with related Telnet optio...
