Opposed.
1) CRTSCTS means something quite specific. Rather than
overload that name for something unrelated, create a new
mode bit for the new mode.
2) Most of what's in setserial is useless and irrelevent to
non-PC-motherboard-16550-uart serial ports (the drivers for
which often don't support setserial).
Let's just suck it up and do it the right way.

I don't really care what the name is. "RTS toggle" or
"half-duplex" is what everybody I know calls it.
