[cups.bugs] [LOW] STR #3165: serial backend parameters "bits" and "stop" documentation

[STR New]

In CUPS 1.3.9 backend/serial.c there is
-------------------------------------------
      else if (!strcasecmp(name, "bits"))
      {
       /*
        * Set number of data bits...
        */
-------------------------------------------
and
-------------------------------------------
      else if (!strcasecmp(name, "stop"))
-------------------------------------------

The only CUPS documentation regarding the
serial backend parameters which I know
is the CUPS 1.1 Software Administrators Manual
http://www.cups.org/documentation.php/doc-1.1/sam.html
which reads:
-------------------------------------------
serial:/dev/ttyS0?baud=9600+size=8+parity=none+flow=soft
-------------------------------------------

I.e. "bits" is documented as "size"
and "stop" is not documented at all.


By the way, an enhancement request:

It would be nice if all backends report their
possible parameter settings (keywords + values)
when they show their "Usage" info.
