4.2.4-1 GNUPLOT, 3.0.3 Octave Behaviour

[gennarim]

Gentlemen:

I know this problem has been seen before and solved,  but I could not 
find
the solution in any of the archived discussions.  If you have time, 
please
advise. The jist of the matter is as follows:

                          PC/Intel 448 Mhz.OS: Windows 98SE
Cygwin Operating System BASH Layer: 2.1.15
                            Octave Application:   3.0.3
                       GNUPLOT Application:   4.2.4-1


Run Octave:

          Assign;  x= values
Simple plot command:  plot(x)


Within OCTAVE window :
  GNUPLOT  generates  'set terminaal aqqua 1 enhanced'  message
  GNUPLOT  gemerates  'set terminal type first'         message
  GNUPLOT  enumerates the X array with error messages.
..
  OCTAVE prompt returns.

  GNUPLOT     plot window does not open
  GNUPLOT  command window does not open.

Within OCTATVE:

Tried  setenv("GNUTERM","unknown")
  Result: Same plot error: had no effect

Tried  setenv("GNUTERM","vttek")
  Result: Generate character output in OCTAVE WINDOW,no plot

Tried  setenv("GNUTERM","")
  Result: Generated character stream output in OCTAVE window, no plot

> From CYGWIN OS,

Tried  export GNUTERM="unknown". then OCTAVE, then plot(x); ERROR/halt
Tried  export GNUTERM="".        then OCTAVE, then plot(x); ERROR/halt
..
etc. with ERROR/halt, no plot..


Sincerely,
MJG
