More VMS - test-drb@ccmp.vtda.org

27 Mar 2002

Whats hardware dependent about the VMS version?  The unix version
assumes a locally connected "head" or a Xserver/Xterm system.

The terminal can be others as I belive some of the later VT clones
also had it.  Also if you running a DEC system that has a "head"
that implied terminal does both DECwindows and Multisessions.

 also support this with more common VT220s or VT320s.
 I was added late in  VMS 4.mumble and later versions.
 This is not decwindows which is GUI based.

 What multisession allows is several virtual terminals over several
 virtual circuits using one terminal and physical circuit.  I use it alot. 
  Yeah, that's pretty much what I was talking about.  The Unix screen
tool is hardware-independent, though.  The host manages the virtual
sessions and display.  I have an RS/6000 that's usually running with an
IBM 3151 [1] terminal, and screen & su allow me to be several users or
run several login sessions.
  An additional feature of screen is its "detach" function.  You can log
in remotely, start screen, start a job that doesn't support detach,
detach the screen session, and log out.  Log in later, reattach from
screen, and watch your job.  Yes, I'm familiar with nohup, but this is
more convenient if I'm actually watching output.

[1] - What am I missing here?  AFAICT, the 3151 is the lamest, most
featureless serial terminal of its time.  No options, no usefull
emulations, really bad CRT.  Bleah!
