TELNET OUTPUT LINEFEED DISPOSITION

1. Command name and code NAOLFD 16 (Negotiate About Output Linefeed Disposition)

2. Command meanings In the following, we are discussing a simplex connection, as described in the NAOL and NAOP Telnet Options. IAC DO NAOLFD The data sender requests or agrees to negotiate about output linefeed 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 linefeed considerations. IAC DON’T NAOLFD The data sender refuses to negotiate about output linefeed disposition with the data receiver, or demands a return to the unnegotiated default mode. IAC WILL NAOLFD The data receiver requests or agrees to negotiate about output linefeed 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 linefeed considerations. IAC WON’T NAOLFD The data receiver refuses to negotiate about output linefeed disposition, or demands a return to the unnegotiated default mode. IAC SB NAOLFD DS <8-bit value> IAC SE The data sender specifies, with the 8-bit value, which party should handle output linefeeds and what their disposition should be. The code for DS is 1. IAC SB NAOLFD DR <8-bit value> IAC SE The data receiver specifies, with the 8-bit value, which party should handle output linefeeds and what their disposition should be. The code for DR is 0.

3. Default DON’T NAOLFD/WON’T NAOLFD. In the default absence of negotiations concerning which party, data under or data receiver, is handling output linefeed considerations, neither party is required nor prohibited from handling linefeeds; but it is appropriate if at least the data receiver handles them, albeit primitively.

4. Motivation for the Option Please refer to section 4 of the NAOL and of the NAOLFD Telnet option descriptions.

5. Description of the Option The data sender and the data receiver use the 8-bit value along with DS and DR SB commands as follows:

8-bit value Meaning

0 Command sender suggests that he alone will handle linefeeds, for the connection. 1 to 250 Command sender suggests that the other party alone should handle linefeeds, 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 qualifications, below.) 251 Not allowed, in order to be compatible with related Telnet options. 252 Command sender suggests that the other party alone handle linefeeds, but suggests that they be discarded. 253 Command sender suggests that the other party alone should handle linefeeds, but suggests that linefeeds be simulated. 254 Command sender suggests that the other party alone should handle output linefeeds but sugges...
