Hello

I am bringing up some new hardware and need a simple method to toggle the RTS line on the output of a serial device 
(uart 16550). I looked at the online help and found that the utility stty used to provide this functionality but not in 
6.4.1 which I am using.

Is there an alternative method, I could do this programmatically (could you provide an example) but would also like a 
command line option for scripting purposes.
Thanks for your help
