and stop bits) are omitted from the output.
(This option applies to \-\-rx mode only).
.TP
.B \-\-binary-raw {nbits}
Print all received bits (data bits and any framing bits) as raw binary output
using characters '0' and '1'. Framing bits are not interpreted, but simply
passed through to the output. The bits are printed in the order they are
received, in lines {nbits} wide. So in order to display a standard 8-N-1
bitstream (8 databits + 1 start bit + 1 stop bit), use "--binary-raw 10"
or a multiple of 10.
(This option applies to \-\-rx mode only).
.TP
.B \-\-print-filter
Filter the received text output, replacing any "non-printable" bytes
with a '.' character.
