[Twisted-Python] serialport protocol as a service

[Aníbal Pacheco]

Hello list,

Is there any way to get a service like the twisted.internet.TCPServer 
but for serialport?

I read the serialport code but couldn't figure out how to build such an 
analogy with the tcp server.

The goal I wanna reach is to attach this "serial port service" to my 
service.MultiService object which already works great with a TCPServer 
and two TimerService

thanks!
