 jv> ml> oooooo... question for you...

 jv>     Let's see what help you can get from me...

 jv> ml> the PING and Tyz flags appear in the Z2 prolog _under_ the
 jv> ml> "approved user flags" heading... does this mean
that they are only
 jv> ml> U,ser flags and not normal flags in Z2?

 jv>     The PING and Tyz flags appear in the Z2 prolog:
 jv>         _below_ the "user flag" definition
 jv>     but _above_ the "approved user flags" heading

 jv>     Thusly they're not user flags.

hummm... reading what you've written, it would appear that they /are/
¨userflags... just not _approved_ userflags...

 jv>     That was an easy one, was it not?

seems that way... just looking for confirmation and information...

 jv> ml> i also note that the Z2 prolog doesn't state that the IEM flag is
 jv> ml> depricated like FTS-5001 states... i've not noted the IEM flag used
 jv> ml> in Z2 but do note the EMA flag appearing to be used in the same
 jv> ml> type vein as IEM...

 jv>     Z2 has nearly one hundred IEM flags flying, even the ZC
 jv> himself. If you have a problem with that, please ask Ward.

not a problem... what i was noting is that EMS shows up in my
"error" ¨reports... those IEM flags must be "properly"
implemented in so far as my util ¨currently checks for them...

 jv> ml> additionally, i personally note that V42B does not imply V42
 jv> ml> capability... one is error correction and the other is data
 jv> ml> compression and neither relies on the other or implies the other...
 jv> ml> does Z2 view them differently? if so, why?

 jv>     As far as I know, that relation has been in the
 jv> nodelist for at least 10 years so I assume there is a good
 jv> reson for that.

 jv>     Maybe because modems were marketed that way?

v42 and v42b are protocols... like v90 and mnp and exactly that way... one
is ¨data compression and the other is error correction... the specs for
each do ¨not define the other as necessary or a mandated fallback
capability...

from what i've seen over all these years, they got "grouped"
together simply ¨because the ITU-T (can't remember their original name)
used 42 in both of them ¨and the average layman wasn't able to tell that
they weren't related...

 jv> ml> FWIW: yes, i'm working on a nodelist analysis util...

 jv>     With what purpose beyond fun?

to look at "strict adherence to the published specs" concerning
the nodelist ¨format and flags used in it...
