mcfserial will process and remove the XON/XOFF chars if software flow
control is enabled.  If not,  they will be passed through to the
application like normal chars.

Actually,  the processing is not actually done in mcfserial but in the line
discipline,  another kernel driver,  but the effect for a user application
is the same.
