RTS/CTS flow control (AIX V3)

[Kevin P. Kleinfelter]

How does one enable/disable RTS/CTS flow control on a tty line using
AIX V3, from a C program?  The only info provided by "info" is that
"stty add rts" can be issued from the shell level.

I have issued "stty add rts" from the shell, then entered a C program that
puts the terminal in raw mode, and it appears that RTS/CTS flow control
is not enabled.  That is to say, a line monitor shows that data is
received, RTS is not dropped, yet the last few bytes of the data are
not returned by a "read" in my code.

"info" has references to RTS within ioctl, but it only tells how to examine
the bit, not how to tell the driver to manage RTS/CTS flow control.

HELP.
