To command T100+ to
tune to a specific
frequency, the host
program shall transmit
a six-digit frequency
in ASCII characters
via the serial port.
To command T100+ to take a measurement, send
an ASCII character ‘S’. Then receive from
the serial port a null terminated ASCII
string. This is the measured magnitude and
argument in degrees, separated by a comma.
The same result will be displayed on T100+
at the same time.
Send another ‘S’ to repeat making a
measurement at the same frequency, or issue
another six-digit frequency to tune to a new
frequency.
Sending an ASCII character ‘D’ will bring
T100+ back to the initial state, displaying
the “WAITING FOR HOST CMD” message and
listen to the serial port.
