Coolterm Capture analog in and resend

Hi,
has anyone had any experiences with Coolterm.
My setup is as follows.
Potentiometer connected to AnalogIn, like A0 and a servo on the output side, just
like Knob example.
I used line Serial.print(analogRead(0)); Serial.print('\t');
to send data to Coolterm. I'v enabledTimestamps to capture Raw data.
Capture to textfile in Coolterm
and then I tried to send "recorded data" back to Servo.
The result was not what I expected, I didn't get the movements
I'v recorded, servo was erratically moving
Please help

Your code might be bad, your wiring might be bad, your servo power supply might be inadequate.
