GNO/ME wasn't really designed with the
|
||
|
|
intention of making
|
||
|
|
<emphasis>every</emphasis>
|
||
|
|
program you currently run work under
|
||
|
|
GNO/ME; that task would have been impossible. Our main goal was
|
||
|
|
to provide a UNIX-based multitasking environment; that we have
|
||
|
|
done. We made sure as many existing applications as we had time
|
||
|
|
to track and debug worked with GNO/ME.

|
However, due to the sheer number of
|
||
|
|
applications and authors, there are some programs that just plain
|
||
|
|
don't work; and some that mostly work, except for annoyances such
|
||
|
|
as two cursors appearing, or keyboard characters getting "lost".
|
||
|
|
The problem here is that some programs use their own text drivers
|
||
|
|
(since TextTools output was very slow at one time); since GNO/ME
|
||
|
|
doesn't know about these custom drivers, it goes on buffering
|
||
|
|
keyboard characters and displaying the cursor. There is a way,
|
||
|
|
however, to tell GNO/ME about these programs that break GNO/ME's
|
||
|
|
rules.

||

<para>

|
We've defined an auxType for S16 and EXE
|
||
|
|
files, to allow distinction between programs that are GNO/ME
|
||
|
|
compliant and those that are not. Setting the auxType of an
|
||
|
|
application to $DC00 disables the interrupt driven keyboard
|
||
|
|
buffering and turns off the GNO/ME cursor. Desktop programs use
|
||
|
|
the GNO/ME keyboard I/O via the Event Manager, and thus should
|
||
|
|
<emphasis>not</emphasis>
|
||
|
|
have their auxType changed.
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>
|
||
|
|
You can change a program's auxType with the
|
||
|
|
following shell command:
|
||
|
|
<screen>
|
||
|
|
<command>chtyp -a \$DC00</command> <filename>filename</filename>
|
||
|
|
</screen>
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>
|
||
|
|
where <filename>filename</filename> is the name of the
|
||
|
|
application. As more programmers become aware of GNO/ME and work
|
||
|
|
to make their software compatible with it, this will become less
|
||
|
|
of a problem, but for older applications that are unlikely to
|
||
|
|
ever change $DC00 is a
|
||
|
|
reasonable approach.
