[Twisted-Python] SerialPort testing on the Twisted build slaves
Hi, Ticket http://twistedmatrix.com/trac/ticket/3690 is adding some serial port testing. The patch adds code to discover serial ports on Windows and Posix and the test uses the first serial port that is discovered. Will this approach work for the build slaves, or is it better to use an environment variable that can be set for each build slave? Do any of the build slaves have serial ports or are they all VMs?

There's also some more stuff about testing serialports on <http://tm.tl/2462>.

Last time I checked things were not in good shape. I don't think we can count on serial ports on any of the slaves right now. VMs might actually be *easier* (at least if we trust that the VM serial port driver behaves roughly like a real serial port driver). Actually convincing slave operators to plug something into a serial port is probably out of reach. Jean-Paul
