Do NOT use ShortString unless you are sure you won't hit the length limit on ShortString.

The illegible characters are called "carriage return" (CR) and "linefeed" (LF), I'm guessing.
They are part of a standard called ASCII. The letters and numbers you see are also part of that standard.
These are all "A B C" beginner things that you will not find so daunting once you have taken a little time to understand what an ASCII serial protocol is.
You read the bytes (in two reads...

So what you want to do is get rid of the terminal component, and just read and write from the com port yourself.
You don't need to emulate "how the terminal component works". You just need to read and write bytes (characters) from the com port.

Or are you asking, how does it work, internally? The thing receiving the information is notified (by an internal "callback"). This is similar to how data aware controls receive their data, from datasets. Callbacks (events) are a key part of component design.

Did you try ComTerminal.WriteStr('String') ?
