Update to ILPer v2.1

[Christoph Giesselink]

Just a short update of ILPer v2 disabling the ESC key and added Jurgens suggestion of increasing the printer width over the scope window area when the scope is disabled.

The result was a printer window with ~74 columns. To avoid any questions "why not 80 columns" I increased the width of the ILPer main window to get an extended printer window with ~80 columns. The real number of column depend on font size, used OS, display driver and other factors. So the resulting no. of columns on your PC may less or more than the nominal 80 columns.

The modified program version and the IPv6 version are available at http://hp.giesselink.com/. I also updated the Virtual HP-IL example at http://hp.giesselink.com/HPIL/ILPer/ILPer.htm with new pictures.
