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).
81A string capability is specified by
82.Em capability Ns Ar = Ns Em value ;
83for example, ``dv=/dev/harris''.
84A numeric capability is specified by
85.Em capability Ns Ar # Ns Em value ;
86for example, ``xa#99''.
87A boolean capability is specified by simply listing the capability.
88.Bl -tag -width indent
89.It Cm \&at
90(str)
91Auto call unit type.
92.It Cm \&br
93(num)
94The data rate (bits per second) used for communications on the
95serial port.
96When a modem is used, the data rate used to communicate
97with the remote modem may be different than this rate.
98This is a decimal number.
99The default rate is 9600 bits per second.
100.It Cm \&cm
101(str)
102An initial connection message to be sent to the remote host.
103For example, if a host is reached through a port selector, this
104might be set to the appropriate sequence required to switch to the host.
105.It Cm \&cu
106(str)
107Call unit if making a phone call.
108Default is the same as the `dv' field.
109.It Cm \&di
110(str)
111Disconnect message sent to the host when a disconnect is requested by
112the user.
113.It Cm \&du
114(bool)
115This host is on a dial-up line.
116.It Cm \&dv
117(str)
118.Ux
119device(s) to open to establish a connection.
120If this file refers to a terminal line,
121.Xr tip 1
122attempts to perform an exclusive open on the device to ensure only
123one user at a time has access to the port.
124.It Cm \&el
125(str)
126Characters marking an end-of-line.
127The default is
128.Dv NULL .
129`~' escapes are only
130recognized by
131.Nm tip
132after one of the characters in `el', or after a carriage-return.
133.It Cm \&fs
134(str)
135Frame size for transfers.
136The default frame size is equal to
137.Dv BUFSIZ .
138.It Cm \&hd
139(bool)
140The host uses half-duplex communication, local echo should be performed.
141.It Cm \&ie
142(str)
143Input end-of-file marks.
144The default is
145.Dv NULL .
146.It Cm \&oe
147(str)
148Output end-of-file string.
149The default is
150.Dv NULL .
151When
152.Nm tip
153is transferring a file, this
154string is sent at end-of-file.
155.It Cm \&pa
156(str)
157The type of parity to use when sending data
158to the host.
159This may be one of ``even'',
160``odd'', ``none'', ``zero'' (always set bit 8 to zero),
161``one'' (always set bit 8 to 1).
162The default is even parity.
163.It Cm \&pn
164(str)
165Telephone number(s) for this host.
166If the telephone number field contains an @ sign,
167.Nm tip
168searches the file
169.Pa /etc/phones
170file for a list of telephone numbers (see
171.Xr phones 5 ) .
172.It Cm \&tc
173(str)
174Indicates that the list of capabilities is continued in the named
175description.
176This is used primarily to share common capability information.
177.El
178.Sh FILES
179.Bl -tag -width /etc/remote -compact
180.It Pa /etc/remote
181The
182.Nm
183host description file resides in
184.Pa /etc .
185.El
186.Sh EXAMPLES
187Here is a short example showing the use of the capability continuation
188feature.
189It defines a 56k modem connection on the first serial port at 115200
190bits per second, no parity using the Hayes command set with standard
191line editing and end of file characters.
192The arpavax entry includes everything in the UNIX-57600 entry plus
193the phone number for arpavax (in this case an @ character so that it
194is retrieved from the environment).

205.Sh HISTORY
206The
207.Nm
208file format appeared in
209.Bx 4.2 .
210.Sh BUGS
211The
212.Xr tip 1
213utility uses its own notion of the serial ports data rate rather than the
214system default for a serial port.
