Hoping to help clarify: I have used dialup connections to an HP3000
extensively over the past six years. Mostly using WRQ Reflection with
anywhere from a 28k to a 56k modem and NS/VT. Not a week goes by that I
do not get disconnected from at least one session - and frequently more.
So it's probably not QCTerm or Telnet, per se.
When this happens, try doing a tracert - I invariably find *extremly*
long ping times from some node, or nodes, in the path. (Occasionally
that node is the HP3000 itself).
