I’m currently using the SerialPort connection type in twisted 15.5.0 with python 2.7.7 on a windows machine.

Twisted serial communications with the serial port fail when pyserial is upgraded from 2.7 to 3.0.1 and fails with the following error.

Hi,

I think that this is a know issue.

Please see https://twistedmatrix.com/trac/ticket/8159

It would help if you could try the patch and report that all is ok for your use case.

If not the same issue, please report a new ticket.
