Possibly ... if the phone circuit regularly had noise in only one
direction then you would see this kind of behaviour.

What's more likely is that your machines aren't "equal".  That is,
uunet is more able to recieve large bursts of characters than your
system is.

This might be because of small input buffers on your system.  Poor
implementation of hardware flow control (or no flow control) on your end.
Or your system might be slow.  (Face it.. Sequent's simply do not lack
for CPU cycles... ;-) ...)
