In Nutshell Books' _Managing uucp and Usenet_, in the description of the systems file, it says that BSD 4.3 allows a _grade_ subfield within the _schedule_ field. How is this communicated to the system being called? My guess is that it shows up as another option (along with - Qseq and - xdebuglevel) in the master's Shostname response to the slave's Shere=hostname message -- true? Does anybody know the exact format? Presumably, a slave not running BSD 4.3 simply ignores this option? Also, speaking of Qseq: When, EXACTLY, in the startup sequence is the sequence number incremented? The Nutshell book says it's for every call *attempt*, but this seems unlikely; if I call a neighbor and get a busy signal, and subsequently call and get through, it doesn't seem reasonable that I should have bumped my seq number for the neighbor, as the neighbor won't know that I called and won't have bumped theirs. It must be done when some level of handshaking is done -- but when? When the slave sees <DLE>Shostname - Qseq<NUL> , and the master sees ROK? Or when a protocol is agreed upon? Or when the protocol is started? Or when the call terminates normally? --- Jamie Hanrahan, Simpact Associates, San Diego CA Chair, VMSnet [DECUS uucp] and Internals Working Groups, DECUS VAX Systems SIG Internet: jeh@simpact.com, or if that fails, jeh@crash.cts.com Uucp: ...{crash,scubed,decwrl}!simpact!jeh

Yes. Experimentation shows that 4.3 UUCP puts TWO options on the Shere= line; -pX and -vgrade=X I think the lore is that -vgrade= is (largely) historical. Phil Budne, Boston University
