A month or so ago I posted the following, I was wondering if anyone has taken a look at the "disconnect then cannot reconnect" problem in the port. There is an update to the bug I referenced here that will help the situation, but it won't do any good if the FreeBSD port still has the "disconnect then cannot reconnect" problem with the serial ports.
