I'm trying to use a serial port to communicate with a piece
of hardware that expects 8 bits of data plus parity.  I have
been told that this is not possible on 4.3 BSD - that one
can have 7 bits of data plus parity or 8 bits of data if
you're willing to sacrifice parity, or even 8 bits of data
plus parity if you're willing to sacrifice the stop bit.

Well, I suspect it is quite possible if only you know how to
get the magic code through to the UART.  Does anyone know how
this can be done?  As a desperate alternative, I could live
with 8 bits of data and no parity if I can get two stop bits.

Please copy responses to me.  Thank you.
