I rewired the cable today to see if I'd made a dyslexic mistake, and it
checks out just fine.  I eevn took it completely apart and redid it from
scratch.  It appears that ttym[12] on an IP24 does not behave as the man
page would lead me to believe.

That works, sort-of.  It works -great- in some apps like PINE.  But
XEmacs, vim, and lynx stomp all over it.  It's almost as if the local
serial driver is ignoring XON/XOFF, and is passing them to the
application.

Hm.... I might be able to get ahold of some old Wyse terminals that
$county is phasing[1] out.


[1] They're phasing out Wyse terminals on 19.2k dialup modems and
    replacing them with PCs running Windows and a custom telnet app.  No
    amount of screaming and jumping around could convince them that this
    was a reliability step -backwards-.  Never mind that Suzie Secretary
    can't waste time with AIM and Solitaire on a terminal.
