This solves the problem also here  X11 terminal now works
again as desired. Tested with HOBX11 and XFree86-4.3.0.

The only problem on OS/2 that I can see now (and have allways
seen with gnuplot versions later then 3.7 is the
'command-line-history-problem'.
Probably a timing or synchronisation problem.

After starting gnuplot and 'plot x' I _sometimes_ get:

Terminal type set to 'pm'
gnuplot> plot x
gnuplot> gnuplot>

  instead of

Terminal type set to 'pm'
gnuplot> plot x
gnuplot>

  After getting the double (or sometimes triple or even more) prompt the
 commandline-history no longer works. When entering Cursor-UP I get H
 instead of the last command, Cursor-Left gives K, Cursor-Right gives M,
 Cursor-Down gives P and Del gives S

  Example:

Terminal type set to 'pm'
gnuplot> plot x
gnuplot> gnuplot> HKMPS


Backspace-Key is working correct (sometimes I have to hit it twice
to delete the 'HKMPS' characters but the rest of gnuplot works.

following plot or other commands work as desired but cursor-keys
are broken for the rest of the gnuplot session.

When the PM-Window is large, it's more likely that I see the bug.
When the PM-Window is small the bug is more rare.

Any idea what happens and how to resolve this bug?
