 30.Os
 31.Sh NAME
 32.Nm bthost
 33.Nd look up Bluetooth host names and Protocol Service Multiplexor values
 34.Sh SYNOPSIS
 35.Nm
 36.Op Fl bhp
 37.Ar host_or_protocol
 38.Sh DESCRIPTION
 39The
 40.Nm
 41utility looks for information about Bluetooth hosts and
 42Protocol Service Multiplexor (PSM) values.
 43It gets this information from the
 44.Pa /etc/bluetooth/hosts
 45and
 46.Pa /etc/bluetooth/protocols
 47files.
 48.Pp
 49In host mode, it simply converts between the host names and Bluetooth addresses.
 50The argument can be either a host name or a Bluetooth address.
 51The program first attempts to interpret it as a Bluetooth address.
 52If this fails, it will treat it as a host name.
 53A Bluetooth address consists of six hex bytes separated by a colon,
 54e.g.,
 55.Dq Li 01:02:03:04:05:06 .
 56A host name consists of names separated by dots, e.g.,
 57.Dq Li my.cell.phone .
 58.Pp
 59In protocol mode, it simply converts between the Protocol Service Multiplexor
 60names and assigned numbers.
 61The argument can be either a Protocol Service Multiplexor name or
 62an assigned number.
 63The program first attempts to interpret it as an assigned number.
 64.Pp
 65The options are as follows:
 66.Bl -tag -width indent
 67.It Fl b
 68Produce brief output.
 69.It Fl h
 70Display usage message and exit.
 71.It Fl p
 72Activate protocol mode.
 73.El
 74.Pp
 75The
 76.Nm
 77utility will print results to the standard output, and error messages to the
 78standard error.
 79An output can be quite different,
 80here is an example that demonstrates all of the possibilities:
 81.Bd -literal -offset indent
 82% bthost localhost
 83Host localhost has address FF:FF:FF:00:00:00
 84% bthost ff:ff:ff:00:00:00
 85Host FF:FF:FF:00:00:00 has name localhost
 86% bthost -b localhost
 87FF:FF:FF:00:00:00
 88% bthost -b ff:ff:ff:00:00:00
 89localhost
 90% bthost do.not.exists
 91do.not.exists: Unknown host
 92% bthost 0:0:0:0:0:0
 9300:00:00:00:00:00: Unknown host
 94% bthost -p sdp
