Xon/Xoff thresholds

[Brian Varney <brian.varney@xxxxxxxxxxxx>]

Hello all,

I searched around but could not find this information.  Does anybody here know:

1.  Number of byes left in the FT232R chip's RX buffer when it sends XOFF?

2.  Delay between when FT232R chip recieves XOFF until it stops transmitting characters?  I assume this is pretty instantaneous, but is it possible for some TX characters to get through when using high baud rates?

3.  Are either of these values configurable?

I'm working on a device that will be talking to this chip at 921600 baud and want to use XON/XOFF.  This will help determine how quickly we must react to an incoming XOFF and at what point we need to send XOFF.

Thanks,

Brian V.
