TELNET OUTPUT FORMFEED DISPOSITION OPTION RFC 655, NIC 31158 (Oct. 25, 1974) D. Crocker (UCLA-NMC) Online file: [ISI]<DCROCKER>NAOFFD.TXT

TELNET OUTPUT FORMFEED DISPOSITION OPTION

1. Command name and code NAOFFD - 13 (Negotiate About Output Formfeed 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 NAOFFD The data sender requests or agrees to negotiate about output formfeed 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 formfeeds. IAC DON’T NAOFFD The data sender refuses to negotiate about output formfeed disposition with the data receiver, or demands a return to the unnegotiated default mode. IAC WILL NAOFFD The data receiver requests or agrees to negotiate about output formfeed 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 formfeeds. IAC WON’T NAOFFD The data receiver refuses to negotiate about output formfeed disposition, or demands a return to the unnegotiated default mode. IAC SB NAOFFD DS <8-bit value> IAC SE The data sender specifies, with the 8-bit value, which party should handle formfeeds and what their disposition should be. The code for DS is 1. IAC SB NAOFFD DR <8-bit value> IAC SE The data receiver specifies, with the 8-bit value, which party should handle formfeeds and what their disposition should be. The code for DR is 0.

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

4. Motivation for the Option Please refer to section 4 of the NAOL and of the NAOFFD 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 formfeeds, for the connection. 1 to 250 Command sender suggests that the other party alone should handle formfeeds, but suggests that 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. 251 Command sender suggests that the other party alone handle formfeeds, but suggests that each occurrence of the character be replaced by carriage-return/line-feed. 252 Command sender suggests that the other party alone handle formfeeds, but suggests that they be discarded. 253 Command sender suggests that the other party alone should handle formfeeds, but suggests that f...
