Heather wants the device to be in half-duplex mode where it does not echo the serial port characters. Unfortunately in version 5 the command that it sends to turn echo off does not work on all receivers. It is fixed in the next version.
Right now, try starting heather with the /rx5 /bt command line options. The /bt will start Heather in a terminal emulator mode. Type in the command (without the quotes):
Type in "SYST:STAT?" and verify that what you typed is not echoed. Press END to exit terminal mode.
