38.Sh NAME
39.Nm remote
40.Nd remote host description file
41.Sh DESCRIPTION
42The systems known by
43.Xr tip 1
44and their attributes are stored in an
45.Tn ASCII
46file which
47is structured somewhat like the
48.Xr termcap 5
49file.
50Each line in the file provides a description for a single
51.Em system .
52Fields are separated by a colon (``:'').
53Lines ending in a \e character with an immediately following newline are
54continued on the next line.
55.Pp
56The first entry is the name(s) of the host system.
57If there is more
58than one name for a system, the names are separated by vertical bars.
59After the name of the system comes the fields of the description.
60A field name followed by an `=' sign indicates a string value.
61A field name followed by a `#' sign indicates a numeric value.
62.Pp
63Entries named ``tip*'' and ``cu*'' are used as default entries by
64.Xr tip 1 ,
65and the
66.Xr cu 1
67interface to
68.Nm tip ,
69as follows.
70When
71.Nm tip
72is invoked with only a phone number, it looks for an entry
73of the form ``tip300'', where 300 is the data rate with
74which the connection is to be made.
75When the
76.Nm cu
77interface is used, entries of the form ``cu300'' are used.
78.Sh CAPABILITIES
79Capabilities are either strings (str), numbers (num), or boolean
80flags (bool).  A string capability is specified by
81.Em capability Ns Ar = Ns Em value ;
82for example, ``dv=/dev/harris''.
83A numeric capability is specified by
84.Em capability Ns Ar # Ns Em value ;
85for example, ``xa#99''.
86A boolean capability is specified by simply listing the capability.
87.Bl -tag -width indent
88.It Cm \&at
89(str)
90Auto call unit type.
91.It Cm \&br
92(num)
93The data rate (bits per second) used for communications on the
94serial port.
95When a modem is used, the data rate used to communicate
96with the remote modem may be different than this rate.
97This is a decimal number.
98The default rate is 9600 bits per second.
99.It Cm \&cm
100(str)
101An initial connection message to be sent to the remote host.
102For example, if a host is reached through a port selector, this
103might be set to the appropriate sequence required to switch to the host.
104.It Cm \&cu
105(str)
106Call unit if making a phone call.
107Default is the same as the `dv' field.
108.It Cm \&di
109(str)
110Disconnect message sent to the host when a disconnect is requested by
111the user.
112.It Cm \&du
113(bool)
114This host is on a dial-up line.
115.It Cm \&dv
116(str)
117.Ux
118device(s) to open to establish a connection.
119If this file refers to a terminal line,
120.Xr tip 1
121attempts to perform an exclusive open on the device to ensure only
122one user at a time has access to the port.
123.It Cm \&el
124(str)
125Characters marking an end-of-line.
126The default is
127.Dv NULL .
128`~' escapes are only
129recognized by
130.Nm tip
131after one of the characters in `el', or after a carriage-return.
132.It Cm \&fs
133(str)
134Frame size for transfers.
135The default frame size is equal to
136.Dv BUFSIZ .
137.It Cm \&hd
138(bool)
139The host uses half-duplex communication, local echo should be performed.
140.It Cm \&ie
141(str)
142Input end-of-file marks.
143The default is
144.Dv NULL .
145.It Cm \&oe
146(str)
147Output end-of-file string.
148The default is
149.Dv NULL .
150When
151.Nm tip
152is transferring a file, this
153string is sent at end-of-file.
154.It Cm \&pa
155(str)
156The type of parity to use when sending data
157to the host.
158This may be one of ``even'',
159``odd'', ``none'', ``zero'' (always set bit 8 to zero),
160``one'' (always set bit 8 to 1).
161The default is even parity.
162.It Cm \&pn
163(str)
164Telephone number(s) for this host.
165If the telephone number field contains an @ sign,
166.Nm tip
167searches the file
168.Pa /etc/phones
169file for a list of telephone numbers (see
170.Xr phones 5 ) .
171.It Cm \&tc
172(str)
173Indicates that the list of capabilities is continued in the named
174description.
175This is used primarily to share common capability information.
176.El
177.Sh EXAMPLES
178Here is a short example showing the use of the capability continuation
179feature.
180It defines a 56k modem connection on the first serial port at 115200
181bits per second, no parity using the Hayes command set with standard
182line editing and end of file characters.
183The arpavax entry includes everything in the UNIX-57600 entry plus
184the phone number for arpavax (in this case an @ character so that it
185is retrieved from the environment).

204.Sh HISTORY
205The

207file format appeared in
208.Bx 4.2 .
209.Sh BUGS
210The
211.Xr tip 1
212utility uses its own notion of the serial ports data rate rather than the
213system default for a serial port.
