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

The packet ends when there is just no more data to read.

What I meant by 'Hex Data' is that I am reading data in the form of bytes but
they do not represent ASCII characters.
So if I read a $0D, it's just a byte $0D, it doesn't represent a carriage

What exactly do you mean by HEX Bytes?
Hex

I have struggled with LazSerial in a console
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)
I'm trying to figure out how to read a packet of HEX Bytes of an unknown
length that have no specific termination character over a serial port as
efficiently as practical.

I have something that is working that I wrote using SerRead from the
