Quite so! My experience is as follows: if your machine's serial ports
will support the de-facto-standard RTS/CTS hardware flow control, use
it... enable it on your machine, and configure the Telebit modem to
use this form of flow control.
If your machine does not support RTS/CTS flow-control, do NOT use
XON/XOFF flow control during UUCP connections (spoofed or otherwise).
Instead, tell the Telebit to use NO flow control whatsoever!
This is often a very important step. If you configure the Telebit to use
RTS/CTS flow control, and your host doesn't support it, you'll almost
certainly lose data during non-spoofed UUCP transfers. If you configure
for XON/XOFF flow control, neither spoofed nor non-spoofed UUCP transfers
will work correctly, as Larry pointed out. Saying "No flow control, please"
is much safer than requesting a flow-control which either does not work
or is incompatible with the higher-level protocols.
At least, this is my experience with a TrailBlazer Plus.
