Network Working Group D. Walden Request for Comments: #591 BBN-Net NIC: #20327 29 November 1973

        Addition to the Very Distant Host Specification

 It has been brought to my attention that the following sentence

should be added to the Very Distant Host specification in Appendix F of BBN report 1822, Specifications for the Interconnection of a Host and an IMP, to the paragraph beginning on page F-5 and ending on page F-7:

"Null packets do not use a channel (nor a channel number) when sent and are not acknowledged when received."

 Please file this RFC with your copy of BBN report 1822 until 1822

is next updated.
