[syslinux] extlinux 6.03 serial console not responding to input

> The documentation should mention only the currently supported formats though.
 
Documentation can be found in several forms, and, generally speaking, 
the most "current" one is the official wiki.

The wiki serves for any version, not just the latest. When appropriate, 
specific (ranges of) versions are mentioned.

The non-decimal values for the SERIAL directive are supposed to be 
supported, and hopefully a patch will correct this regression bug.

Modifying the main documentation according to bugs could cause 
confusion, and maintaining clear (i.e. understandable and not outdated) 
documentation takes time too.

So, the main documentation of the SERIAL directive should remain, clear 
and concise.

Yet, I agree. Considering that now we know what is happening, and that 
there are workarounds available for common users (until the bug is 
corrected), users would benefit from documenting the potential 
problematic behavior, and possible workarounds.

Thus, a new (basic, simple) section has been created already 
 http://www.syslinux.org/wiki/index.php/Common_Problems#Serial 

and relevant references (links) have been added in other places in the 
official wiki.

Ady.
