I've got still more information to report...
I've eliminated everything from my program except the serial sending
routine. I still get the lockups. Using Shark, I've found that
during the lockup periods there are several hundred calls to a
routine in my serial driver called "FTDIUSBSerialDriver::getUSBDevice
()". My first response would be... "Well, there you go... its a bad
serial driver.", except that it works great in RealBasic 2.5.5, so
I'm not buying that so quickly.
FWIW: Do you have the latest version of the FTDI OSX driver? I've had
cases where the entire Mac would luck up under certain conditions
(mostly related to the USB device itself). The older versions of the
OSX drivers definately had some problems vs the Windows drivers. I've
yet to have a lockup with the latest driver, however.
That said, from your description sure sounds like something in RB is
getting locked into a loop, waiting for something to happen with the
USB driver. (which could be a pure RB issue, or could be an RB issue
triggered by the driver)
