Hi Quentin.
Yes I do want to increase the number of lines in the scrollback buffer for
the terminal. I am using cygwin and I can confirm that the terminal
emulator is rxvt. So your suggestion to set rxvt*saveLines should do it.
However, I am too ignorant to follow your instructions to set this. I don't
have a .Xdefaults file already and I don't know which is the relevant home
directory. The most relevant directory I can find is:
C:\Program Files\GNU Octave 2.1.73\usr\share\terminfo
Can you please give me any further advice?
