We have found a public domain program called "screen" by Oliver Laumann to 
be very useful.  It allows the user to have multiple full screen vt100 
windows and switch between them.  The vt100 emulation is very good.  It 
also allows the user to detach and later resume a screen session.  This 
last feature is very useful for dialup lines.  If the connection is lost, 
the user merely redials and then resumes the previous screen session.  No 
work is lost.  

This is not meant to be a full description of screen's capabilities.  It is
available from comp.sources.unix which are archived at uunet.uu.net and other 
locations.  There was an IRIS port by Jim Barton.
