Why not using the solution they place there?
<quoting their wiki page> Windows
Unfortunately, these objects have not yet been compiled for Windows. Until they are, you can use a small utility program that receives incoming serial data and sends it to a network port as UDP data.
serialosc2udp.ziphttp://ccrma.stanford.edu/courses/250a/pd/serialosc2udp.zip .
Copy the file serialosc2udp.exe to your C:\ccrma\bin
Open the Windows command window and Run from the command line:
"serialosc2udp.exe COM# localhost 999" where '#' is your serial com port number.
Shut down your firewall
In Pd, make sure you have the standard OSC objects installed. Create a
"dumpOSC" object with port "999" as the argument.

Or you wanted a single object that could perform that in Windows?
<quoting their wiki page> Or, you can download the source from pd_OSCserial_src20070810.tar.gz<http://ccrma.stanford.edu/courses/250a/pd/pd_OSCserial_src20070810.tar.gz>. If you want to develop these objects at CCRMA with the subversion repository, you must belong to the pid group. E-mail gurevich (at) ccrma and carrlane (at) ccrma to request to be added to the group. </quoting their wiki page>
Or... you can always try to compile the source in windows and make the needed changes.

sing an AVRmini board to pass data from several sensors to pd via OSC (USB), and I can do it on Linux with the objects pd_OSCSerial
