[Twisted-Python] Reconnection to Serialport after connectionLost

[Thorne, Stephen]

Last I looked at this I had problems with the disconnection events not
being propagated properly. I did, however, end up being able to write
a system that would connect, disconnect and reconnect to usb serial
devices that went away and came back again. So I'm sure it's possible.

Can't access that code anymore, sorry.

Stephen.
