Doug,

there is an OS-9 system call that you could use to enable RTS/CTS flow control.

The name of the call is I$SetStt. Among others, there are function codes
available to disable and enable the RTS hardware handshake lines. From C, you
can use that call by calling _os_ss_dsrts(path) to disable or
_os_ss_enrts(path) to enable RTS (see your C-library manual). Of course, this
requires that your driver as well as your hardware support RTS. You could
simply try it, or consult your hardware manufacturer, in case your manuals
don't tell you enough about RTS and CTS (mine don't, I'm using an ELTEC board
right now). They should be able to help you.

Regards,

Jost
