Forgot to add a question regarding making this a cross-platform
program:
If I add a check for the platform inside my program, how sghould it
look like to work on both Windows and Linux?
Something like this:
function TWiFiCommTester.ConnectSerial(Port: byte; Baud: integer):
boolean;
var
ComportName: string;
Flags: TSerialFlags;
begin
FLastError := '';
{$IFDEF WINDOWS}
ComPortName:= '\\.\COM' + IntToStr(Port);
{$ENDIF}
{$IFDEF UNIX}
//What goes here?
ComPortName :=
{$ENDIF}
FSerial := SerOpen(ComPortName);

Sorry Bo and Paul, I mailed you directly when I meant to reply here.
This rolls up the messages from earlier.

to \\.\COM255 will work
Which is something that I pointed out to you, although in my case I
think I only tested up to 12 (i.e. with an 8-port card).
What comes after 255: 0 or 1? If 0 which form or name does it require?
> I have yet to complete other parts of the application so I don't

Note that that unit was specifically written to be usable either with or
without separate communications threads. If you're /not/ using threads
then there's a callback so that the read-with-timeout functions can
periodically call Application.ProcessMessages, and that the places that
it is used are OS-specific. You obviously /don't/ want to use that
callback if the comms functions are in their own threads, since APM
should only be called from the main thread.
I'm probably losing this email address on Tuesday, if there's anything
that you think I can possibly clarify please raise it sooner rather than
later.

OK, but this is something that the application programmer needs to be
aware of. I suppose it would be possible to modify the unit so that if
it sees a trailing : it changes it to a leading \\.\ if there isn't one
there already, but since the exact names are OS-specific and since we're
already insisting that the application programmer or user puts in /dev/
for unix I'm not sure that's justifiable.
In any event I'm not in a position to do any mods right now and am
probably about to lose access to Solaris (which is probably still worth
testing against) permanently.

Re: [Lazarus] Lazarus Release Candidate 1 of 2.0

[Lazarus] IDE Spotter
Hello, I've polished something that was started during the Lazarus Pro conference in Bonn the last days, the IDE Spotter (this is a "Working Title"). The idea is to have a command box such as it exists in Atom or Visual code studio. Press ALt-Shift-P (or Meta-Shift-P on Mac) to access it. Type the command you wish (e.g. open), navigate with arrows or click on the correct match. The command will be executed. You can type multiple words. all parts must be matched (and are colorized). You can find the package under 'components/idespotter' in SVN. It should also work under 1.8.4/2.0rc1 for those that want to try it. There are some options under Tools - Options - Environment - IDE Spotter. Ideas for improvements are currently: - Shrink window list if the match list is "small". - Search in recent files (projects/units/packages) - ... ? Please testdrive it. Ideas for improvements/comments/bugreports welcome (well, the latter not so much ;)). Thanks go to James Ralston for pitching the idea, and Mattias for including it in SVN !
