FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

      bthost - look up Bluetooth host names and Protocol Service Multiplexor


      bthost [-bhp] host_or_protocol


      The bthost utility looks for information about Bluetooth hosts and Proto‐
      col Service Multiplexor (PSM) values.  It gets this information from the
      /etc/bluetooth/hosts and /etc/bluetooth/protocols files.
      In host mode, it simply converts between the host names and Bluetooth
      addresses.  The argument can be either a host name or a Bluetooth
      address.  The program first attempts to interpret it as a Bluetooth
      address.  If this fails, it will treat it as a host name.  A Bluetooth
      address consists of six hex bytes separated by a colon, e.g.,
      “01:02:03:04:05:06”.  A host name consists of names separated by dots,
      e.g., “”.
      In protocol mode, it simply converts between the Protocol Service Multi‐
      plexor names and assigned numbers.  The argument can be either a Protocol
      Service Multiplexor name or an assigned number.  The program first
      attempts to interpret it as an assigned number.
      The options are as follows:
      -b      Produce brief output.
      -h      Display usage message and exit.
      -p      Activate protocol mode.
      The bthost utility will print results to the standard output, and error
      messages to the standard error.  An output can be quite different, here
      is an example that demonstrates all of the possibilities:
            % bthost localhost
            Host localhost has address FF:FF:FF:00:00:00
            % bthost ff:ff:ff:00:00:00
            Host FF:FF:FF:00:00:00 has name localhost
            % bthost -b localhost
            % bthost -b ff:ff:ff:00:00:00
            % bthost do.not.exists
            do.not.exists: Unknown host
            % bthost 0:0:0:0:0:0
            00:00:00:00:00:00: Unknown host
            % bthost -p sdp
            Protocol/Service Multiplexor sdp has number 1
            % bthost -p 3
            Protocol/Service Multiplexor rfcomm has number 3
            % bthost -bp HID-Control
            % bthost -p foo
            foo: Unknown Protocol/Service Multiplexor


      The bthost utility exits 0 on success, and >0 if an error occurs.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
