Most boards with a RS232 port will have RTS signals, controlled by a port
pin on the microcontroller (i.e., you need to activate it yourself - you
don't get automatic hardware handshaking).
Also, most microcontrollers do not have parity generation as such, but many
allow 9-bit characters. It amounts to the same thing - the ninth bit is in
the same place as a parity bit, and you can control it directly from your
software.

Hello,
I need an eval. board preferably with 68HC11/12 that has full fledged RS232,
most importantly RTS and parity manipulations -- changing mark parity to
space parity from one byte to next. Do you know any such eval. board?
Thanks!
