Syntax of port parameters string:
  -                       - use driver's defaults for all parameters
  *                       - use current settings for all parameters
  <par>=<val>[,...]       - set value <val> for each parameter <par>

Parameters:
  PortName=<portname>     - set port name to <portname>
                            (port identifier by default)
  EmuBR={yes|no}          - enable/disable baud rate emulation in the direction
                            to the paired port (disabled by default)
  EmuOverrun={yes|no}     - enable/disable buffer overrun (disabled by default)
  EmuNoise=<n>            - probability in range 0-0.99999999 of error per
                            character frame in the direction to the paired port
                            (0 by default)
  AddRTTO=<n>             - add <n> milliseconds to the total time-out period
                            for read operations (0 by default)
  AddRITO=<n>             - add <n> milliseconds to the maximum time allowed to
                            elapse between the arrival of two characters for
                            read operations (0 by default)
  PlugInMode={yes|no}     - enable/disable plug-in mode, the plug-in mode port
                            is hidden and can't be open if the paired port is
                            not open (disabled by default)
  ExclusiveMode={yes|no}  - enable/disable exclusive mode, the exclusive mode
                            port is hidden if it is open (disabled by default)
  HiddenMode={yes|no}     - enable/disable hidden mode, the hidden mode port is
                            hidden as it is possible for port enumerators
                            (disabled by default)
  AllDataBits={yes|no}    - enable/disable all data bits transfer disregard
                            data bits setting (disabled by default)
  cts=[!]<p>              - wire CTS pin to <p> (rrts by default)
  dsr=[!]<p>              - wire DSR pin to <p> (rdtr by default)
  dcd=[!]<p>              - wire DCD pin to <p> (rdtr by default)
  ri=[!]<p>               - wire RI pin to <p> (!on by default)

The possible values of <p> above can be rrts, lrts, rdtr, ldtr, rout1, lout1,
rout2, lout2 (remote/local RTS/DTR/OUT1/OUT2), ropen, lopen (logical ON if
remote/local port is open) or on (logical ON). The exclamation sign (!) can be
used to invert the value.

Special values:
  -                       - use driver's default value
  *                       - use current setting

If parameter 'PortName=COM#' is used then the Ports class installer will be
invoked to set the real port name. The Ports class installer selects the COM
port number and sets the real port name to COM<n>, where <n> is the selected
port number. Thereafter use parameter RealPortName=COM<n> to change the real
port name.

Examples:
  install - -
  install 5 * *
  remove 0
  install PortName=COM2 PortName=COM4
  install PortName=COM5,EmuBR=yes,EmuOverrun=yes -
  change CNCA0 EmuBR=yes,EmuOverrun=yes
  change CNCA0 PortName=-
  list
  uninstall
  busynames COM?*
