After a research of the current ListView code I suggest a few changes,
that unify the use of an ListView in general.
1) "AllocBy" is a stupid Delphi invention, that better should become
"Capacity". The Capacity property can have a more specific meaning, not
restricted to virtual (OwnerData) li

Replacing:
GetMem (fInputString, (Len + 1) * SizeOf (REChar));
with:
GetMem (fInputString, (Len + 2) * SizeOf (REChar));

I have a question regarding the way Lazarus/Fpc programs are running
on windows:
A few days ago I was testing GPS communications to retrieve accurate
time. I had written a small program that connected to the GPS using
the SdpoSerial component.
All was working OK.
Then I decided to check how the t

How can a user level program do this?
I would have expected an access violation that would have thrown out
the program but not a repeatable bluescreen.
Why not ?
It can invoke a hardware driver function, and that can cause

The answer should be : in no portable unit.
Unit libc doesn't count since it is only for certain legacy reasons, and
Lazarus should NOT use it.

Could Lazarus use the same C wrapper it now uses on Linux since Android is
mostly a Linux distro with different GUI ?

Very likely :-(
BTW, is that a MS-certified driver?
For example if the port is opened at one baudrate bu the source sends

Most probably the driver has not been tested

I think so, in fact Windows Update found a Prolific driver by itself.

When you are doing something soft real time it is a must.
Things like:
