No, I don't think so.  Serial.Poll is just the same thing that the
event loop normally calls for you; you'd use it if you're stuck in a
tight loop but still need to service the serial port.  But for changing
the settings you mention, I've always had to call Serial.Reset.

I don't know; I've never tried calling it when there may be data in the
buffer.  Resetting a serial port is a pretty drastic thing to do,
pretty much equivalent to closing it and reopening it I think.  Use it
when you're changing the serial port settings; use Poll (or nothing at
all) when you just want to send or receive data.

Best,
