Er, don't you mean that xon/xoff are not treated in any special way, i.e., for
flow control, and that they are valid data bytes.  The telebits may be set
(by changing the values of specific registers) to use a variety of flow control
methods, including rcs/cts and xon/xoff.  It is typically set to xon/xoff by
default for non-uucp users.

Huh?

I don't believe that this is true.  Most likely you are either not sending
binary files or your uucp is sending and resending a lot of packets.  Change to
hardware flow control if you can.  What kind of throughput are you getting with
xon/xoff flow control enabled?

I wouldn't recommend this unless you are really sure your serial port can
handle 19200 without dropping characters.

I wouldn't recommend this unless you are sending a lot of UNcompressed files.
