Aw, you found me out! And please *do* comment. That was really the
point of my posting, because they found that certain programs ran MUCH
faster when they did not use RTS/CTS (over a null modem) that when they did!!
=If the data flow across your TrailBlazers doesn't use XON/XOFF then you
=probably wouldn't have encountered the above problems with XON/XOFF.
=Running uucp transfers with PEP-mode spoofing in the TrailBlazers doesn't

=when the transfer begins.
Sure, that's what I've been doing. No wonder I didn't have any trouble!
