Chris,
If it is just having RTS=CTS, a software solution may be possible. E.g.:

so that RTS=CTS.

| It's been a long time since I worked with serial hardware, but isn't there an alternative pair of pins to RTS/CTS? DTR/DTS or something like that? If the Mac sets the other pins you might be able to short them to the RTS/CTS pins. I know I've done (...) (25 years ago, 16-Dec-98, to lugnet.robotics)
