Can I assume then that you are logging into kcdev via modem?? I.e. this
is not actually a (host-to-host news) "feed"??

"Messages numbers" on an ls? Were you ls'ing a news directory, where each 
article has a numbered filename? This does begin to sound like a 
flow-control/buffering problem to me...

Ah, so you are "calling", i.e. presumably on a modem... well, I suspect
that your problem stems from a hardware flow control setting on the EPORTS
card that interfaces the modem to the 3B2. I always have to remember to
turn that off when I call my main 3B2 at work directly (I usually go 
through another machine and either Starlan or ISN over to it). The EPORTS
setting is somewhat independent of normal stty settings, so if this is the
problem, I'm not surprised that your experimentations with "stty" were to no
avail. To check your EPORTS stty setting, just do "epstty -a". This should 
return with either "hfc" (hardware flow control enabled), or "-hfc" 
(disabled). You can disable the flow control with "epstty -hfc".

Your ISN connection is somewhat different than a modem connection -
especially the ISN-to-3B2 part of it, if it uses 3BFIM's (fiber optics).
If on fiber, stty/epstty settings have little to no effect, not even speed, 
and especially not flow control settings.

I don't know if this helps, since I don't know if kcdev has EPORTS, an ISN 
Fiber Interface, or even for sure if you are calling into it via modem (or
some other EPORTS-connected device, perhaps?)...
