s/months/decades/ and you'll understand why my advice was not more 
specific...

Might be worth reading a little bit about the Linux sysfs interface ... 
if the serial ports appear there, it may be possible to (shell command 
version)
echo 1 > /sys/something/ttyusb0/flow_ctrl_something
in which case, opening it as a normal file and writing to it within your 
Ada program will also work.

Again I can't be more specific as I know very little about sysfs, but it 
seems to be a fairly recent/developing area with neat possibilities.
