You are using TThread.Synchronize.
In a console app, it's likely that somewhere else in your main thread
you'll need to call regularly
May be using TBlockSerial from unit synaser from Ararat Synapse ?
( doc: http://synapse.ararat.cz/doc/help/synaser.TBlockSerial.html ,
download: http://synapse.ararat.cz/doku.php/download ).
Given a variable (SynSer: TBlockSerial;), you can test if data is
available with SynSer.CanReadEx(0)
Amazing !

No, in fact the case statement is written only once, in the

Just nitpicking.
Shouldn't "try" be after the "reset" and after the "rewrite"?
Why don't you allow to write an empty string?
Yes, you're right, the Reset/Rewrite should be after the try.
I admit this code is not general, just

Another way is to declare TMyRec as class instead of record.
In this case, you don't need the dereference operator ^ .
No need of new and dispose, just Create and Free, as for TMyRecList.
I don't know if there is a better performance when you use a record,
but as far as I know,
Ooops, wrong url, I just learn know that property could belong to a
global block... ;-)

Is there no way to declare a property to have a default non-zero
value?
I'm not sure but I think the syntax is for this something like
property ReadPacketSize: integer read FPacketSize write FPacketSize default 10;
