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?
