Calling PST when propeller not connected to a PC

Page 101 of the PEK labs book (v 1.2) suggests removing the PropPlug if using it with the 40-pin DIP version, or commenting out the calls in the code if using the Propstick USB. Both actions are to prevent the Propeller from being reset by the USB to serial converter when code tries to send messages to a PC that is not connected to the Prop.
I am putting the polish on a project, and pondering what to do with all of the calls to Parallax Serial Terminal when the Propeller is running alone - not connected to my PC. I am using the Quickstart board. I have had no troubles with unwanted resets so far. In my application, there are some advantages to leaving the calls in place. But, I cannot risk an unwanted reset.
Is there a risk of unintentionally resetting the Propeller on the Quickstart by sending messages to a PC that is "not there" via Parallax Serial Terminal?

There is a check close to the beginning of the code to detect if it is plugged into the USB or not which may help steer you in the right direction.
