Hello,
Would you guys please add a serial communication tutorial in this wiki page:
http://wiki.lazarus.freepascal.org/index.php/Hardware_Access#Serial_Communication
I wrote the parallel part of the tutorial, but I know nothing about
serial comm and I would be very thankful =)
thanks,

System: Intel-P4 / Linux Kernel 2.6.x
Details:
## binutils-2.14 ##
- Builds fine (except some openbsd and sparc-bsd targets) with gcc3.3.5
(suse 9.3)
- Fails when using gcc4.0.2 (Suse10)
Example:

Copy and paste.
OK, that is not very comfortable. I know a new feature for lazde :-)

Hi, I need to perform very fast squareroot (sqrt) operations on double type
nukmbers.
I tried this
function mysqrt(a:double):double;
var y,yn:double;
begin
yn:=a;
repeat
y:=yn;
yn:=(y*y+a)/(2*y);
until abs(yn-y) < 10e-16;
mysqrt:=yn;
end;
but it is quite slow (FPC uses Heron iterations) which is 10
