[ Clay wants to toggle CTS from a C program ]

To the best of my knowledge, there is no way to do this with the
serial drivers supplied with SCO UNIX/ODT-OS.  The code that sets the
CTS line is embedded in the serial driver.  It is tightly tied to the
number of characters in the input and output queues and to some specific
data structures in the sio driver.

The only ioctl()s available turn RTS/CTS flow control off and on: they
do not toggle the actual state of the line.  If you want to do this,
you'll need to hack out your own device driver - FAS is probably a good
place to start.
