So Matt, does this mean that you are a "Universal Serial ghost-Buster"? (-:

Jim,
If you have a USB-based serial port, the symptom of a USB bus reset is
several burst of enumeration on the bus. This usually affects DTR or
RTS on a serial endpoint, and you may use those for keying or PTT. I
see this here occasionally, but always when plugging in the hub that
hosts the USB-serial adapter. The other times, it's a marginal power
supply somewhere in the massive number of USB devices here in the
shack.
I would check to be sure it *never* happens when the USB-serial is
disconnected - IF that's what your serial connection happens to be....
In case you're using a Microsoft Windows product, the USB bus driver
has a mind of its own and might also have bugs related to this type of
behavior. Keep it up to date.
73,
