So right now, when [comport] is open and that device gets disconnected, comport freezes and Pd crashes. My guess is that comport is waiting and therefore blocking. It seems like the select() call should prevent that, any other guesses on how to prevent comport from locking like this? Many arduino users would be very happy.
Is this on linux? It should be non-blocking on Windows. I suppose it crashes only when you try to send something, not if you just pull the cable out. I would have thought that if hardware handshaking was off, the port will send anyway. I seem to remember sending into an oscilloscope probe with no cable present. Select is problematic, as we have seen with recent [tcpserver], checking if each byte can be sent before it goes out slows the whole thing down a lot.
