[Twisted-Python] twisted.internet.serialport

[joy ping]

hi list,
i just did a search for a framwork which would be good for a to be
written application which controlls serialports over webinterfaces. i
found that twisted would be ideal for this. i started to write some code
with mod_phyton but as threading+pyserial+apache didn't worked i had a
closer look at twisted. it seems cool cause it's async. no real need for
threads here. and with twisted-web and livepages some kind of
persistance could be achived. but at the end i found not really much
documentation especially about twisted.serialport and nevow which i
would use as app-server. can someone point me to some docs if they
exists beside the the api-docs.

thanks
