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):

  ":SYST:COMM:SER1:FDUP  0"

Type in "SYST:STAT?" and verify that what you typed is not echoed.  Press END to exit terminal mode.
