INSTALL
Device::Tektronix and tek-fft

Windows
------------
    1. Install ActiveState Perl or Cygwin w/ Perl
    2. Install Win32-API (Needed for Serial Port)
    3. Install Math::FFT
    4. Install Win32::SerialPort 

For Step 2 + 3 you can use PPM if you running the AS Perl
C:\> ppm 
ppm> install Math-FFT
ppm> install Win32-API

For Step 4 you will need to download the module from 
CPAN (www.cpan.org) and follow their directions, or use
the CPAN module :

C:\> perl -MCPAN -e shell
Now setup your CPAN directory to be somewhere easy to find,
because you're going to need to go in there.

cpan> install Win32::SerialPort

This part might fail, then go finish it by hand...
cpan> quit
C:\> cd cpan\build\SerialPort-0.xx
C:\cpan\build\SerialPort-0.19> perl test.pl
C:\cpan\build\SerialPort-0.19> perl install.pl


Now you should be ready to go.   Plug in your scope, set 
the baud rate on the scope to 38,400 and run tek-fft

perl tek-fft
    

Unix
------------
Math::FFT requires the PARI library.  See 
the Math::FFT distribution for more details.

1. Install PARI

For BSD it's in ports somewhere.
For others ....?

2. Install the Perl Modules

$perl -MCPAN -e shell
cpan> install Device::SerialPort
cpan> install Math::FFT

3. Install this module into the global (optional)
$make
$su
$make install

./tek-fft
