Hi Mark,


Thanks for the advice-it did the trick!





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.
