Hi Corona688...
Hmm, neat.
I never considered using 'awk' in its entirety.
Although I have used 'amplitude' and 'centreline' values to plot inside the terminal I intend to use character 32 (space) and 126 (tilde) as the pk-pk amplitude(s) and "N" or "O" as the centreline. This then makes the whole waveform fully editable in any text mode editor. ;o)
I never even considered how Windows would react under my version as I was more interested in a calculator as a 'bc' replacement for CygWin.
I seem to remember you pointing out how badly Windows reacts to many fork()s in a thread since gone.
Thanks for your creation. Once I have gotten to grips with it consider it stolen... ;oD

ffcfstress(1) General Commands Manual ffcfstress(1)
NAME
ffcfstress - constant force stress test for force-feedback devices
SYNOPSIS
ffcfstress [-d <device>] [-u <update rate>] [-f <frequency>] [-a <amplitude>] [-s <strength>] [-x <axis>] [-A] [-o]
DESCRIPTION
ffcfstress stress tests constant non-enveloped forces on a force feedback device. It simulates a moving spring force by applying a fre-
quently updated constant force effect.
Beware, the stress test may damage your device!
OPTIONS
At least one option is required.
-d <device>
The device to test (by default /dev/input/event0).
-u <update rate>
The update rate in Hz (25 by default).
-f <frequency>
The spring center motion frequency in Hz (0.1 by default).
-a <amplitude>
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by default).
-s <strength>
The spring strength factor (1.0 by default).
-x <axis>
absolute axis to test (default: 0)
[0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
-A switch off auto-centering
-o Dummy option, useful when all defaults should be used.
