Does anyone know the spacing of modem status bytes for the FT232BL? 

Thank you.

Pierre

Here is my final answer:

The ft2232H spaces the modem status bytes every 512 bytes rather that
the
expected 64 byte interval of prior chips like the ft245.  Libftdi will
have
to be changed to detect the type of chip connected and adapt the
ftdi_read_data() routine to handle the appropriate spacing between modem
status bytes.

Cheers,
