Is there a way to check user keyboard input in the main program while
action is being done in the server's threads?

The code I first tried did not need to use crt:

  repeat
    Read(ch);
  until (ch='q');

But it acts like Readln(), in that it requires the user to press 'q'
followed by ENTER in order for the loop to break.

Then I used this but it needs the crt unit:

    repeat
      ch := ReadKey;
    until ch='q'; {q}

and now the user just needs to hit q without any follow-up ENTER.
