Serial Comm: Xon Control

I want to implicitly turn the Xon function OFF when I initialize a serial
port via SF. I am using Commdriver.f, Commextend.f and Commresource.f (not
SIO.f).

If a PC com port happens to be setup for Xon/Xoff control, SF does not touch
it. That will cause lost bytes if a binary packet such as MODBUS RTU format.

Where/how to set DCBflags in SF?

What is the preferred set of serial routines to use?

Thanks for any help,
